Summary

• Dragging a folder in the sidebar no longer collapses every folder in the project. A folder drag sorts units (a header plus its rows, or an ungrouped row): other folders slide as blocks, the dragged folder dims in place as the drop slot, and the ghost stays under the cursor.
• Sessions tag groups are real folders now: they drag as units, sessions can be dropped into and out of them, and folder order/collapse persist. Previously a session dragged out of its group silently snapped back.
• With nothing pinned, picking up any row no longer mounts the Pinned section above the list. The drop-to-pin target floats at the top of the scroller with zero layout impact.

Why / Context

Reported: "dragging folders on sidebar is weird and the preview is not where the cursor is because the group collapses and move things around", then "sessions can't drag at all" and "sessions need to be able to drag groups/tags".

Root cause of the ghost offset: picking up a folder collapsed every folder in the project, so rows above the dragged header collapsed and the header moved under the pointer. dnd-kit's layout-shift compensation then scrolled the sidebar by that delta (measured: a 96px scroll jump at pickup); when the sidebar had no scroll room the DragOverlay latched the shifted position and the ghost rode ~160px off the cursor for the whole drag. The old scroll-height spacer only covered the scroll-clamp variant (and assumed 32px rows; they are 28px). The same class of shift happened for every workspace-row drag when nothing was pinned (Pinned header + drop zone mounting above the list: 76px).

Root cause of sessions snapping back: the Sessions lane only persisted order, never host tags, and its folder index helper returned empty for the project-less lane.

How It Works

• hooks/useSidebarDnd/sectionUnits.ts: createSectionUnitSortingStrategy (verticalListSortingStrategy lifted to units; every row of a unit gets the same translate) and closestUnitCenter (collision on the union rect of each unit, resolving to the unit's header). The flat item list and row heights stay exactly as they were at pickup, so nothing can shift the header. SectionDragSpacer and the instant-collapse escape hatch are deleted with the collapse they compensated for.
• The Sessions lane is now a project-shaped lane: buildDashboardSidebarSessions returns { children, workspaces }, DashboardSidebarExpandedProjectContent takes containerId + projectId: string | null and renders both projects and Sessions, and useSidebarDnd treats "sessions" like a project container. Folder rows and host tag settings for the lane use SESSIONS_TAG_SCOPE (sessions:<tag> ids) via sectionScopeForProject / laneProjectIdForScope; deriveTagFolders derives session folders under that scope; the state hook's folder index / top-level items / ensureSectionRow / deleteSection map through it. DashboardSidebarSessionTagGroup is deleted.
• dashboardSidebarSectionSchema.projectId widens from uuid to uuid | "sessions". Without this the folder-row insert threw a SchemaValidationError inside the drop handler that surfaced nowhere; the UI showed the drop as done and a reload reverted it.
• DashboardSidebarPinnedSection with zero pins renders a sticky top-0 h-0 float holding "Drop to pin" (with -mb-3 to cancel the next section's first:mt-0 margin). A drag that started with pins keeps the in-flow section.

Manual QA Checklist

Driven in the dev app over CDP (trusted mouse events), each step checked after a page reload so only persisted state counts:

• Folder drag: ghost top equals header top at pickup, no scroll change; displacement equals unit heights exactly; drop persists; Escape reverts every transform; collapsed folder drags as a header-only unit
• Pre-fix vs fix in a tall viewport (no scroll room): ghost 162px above the pointer with 10/19 folder rows visible → pointer inside the ghost with 19/19 visible
• Sessions: folder "automation" dragged above ungrouped sessions and back, as a block (folder row created, order persisted)
• Sessions: session dragged out of the folder → ungrouped after reload, host tag removed; dragged back under the last member → host tag re-added
• Sessions: folder collapse via chevron persists across reload; expand persists
• Pinned: pickup with zero pins shifts the row 0px (was 76px); pin on the floating target persists; unpin by dragging back persists
• Project folders: four reload-verified moves in the Superset project still land where expected
• Sessions folder rename / color / delete from the folder context menu (unchanged code path, not re-exercised)

Testing

• bun run typecheck (desktop)
• ./scripts/lint.sh
• bun run --cwd packages/i18n check
• bun test for the sidebar, tag-folder utils, sidebar state hook, and section schema suites (202 tests); new tests: sectionUnits.test.ts, sessions builder tests, schema tests for the sessions scope, deriveTagFolders sessions case

Performance

Heavy-drag stress in the dev build (React dev mode) over CDP: 300 pointer moves sweeping the whole sidebar top to bottom and back through both autoscroll zones, plus 400-move ±3px jitter at a unit boundary. Instrumented with a longtask PerformanceObserver, rAF frame counter, HeapProfiler.collectGarbage before/after. Baseline = the same files from origin/main, alternated with this branch in the same app session (A/B/A/B) with nothing else running.

Drag	Baseline: long tasks / ms	This PR: long tasks / ms	fps
Project row, mid-list sweep	13 / 1055, 10 / 790	10 / 868, 13 / 1070	72-78 both
Project folder, full sweep w/ autoscroll	8 / 651, 5 / 402	5 / 429, 4 / 368	89-90 → 94-97
Session row, full sweep (crosses Pinned repeatedly)	16 / 1791, 18 / 1920	17 / 1783, 17 / 1844	70-72 both
Project folder, boundary jitter	4 / 431	1 / 149	106 → 116

No errors, no Maximum update depth recursion, ghost always removed, rAF latency after each run under 10ms. Folder drags got cheaper (nothing collapses/remounts at pickup); row drags are unchanged. The session-row full sweep is the heaviest case on both sides: each pass through the top zone transfers the row into and out of Pinned, and both sides retain ~25MB after GC from that run — pre-existing, noted as a follow-up.

The last commit caches unit rects per measurement in the unit strategy (dnd-kit calls it once per row per move with the same rects array).

Design Decisions

• Collapse nothing at pickup instead of deferring the collapse or disabling dnd-kit's scroll compensation: those keep the folder snap-shut jank and the scroll-height hack; zero layout change removes the whole class of bug.
• Sessions reuse the project lane rather than a parallel implementation: one list component, one DnD strategy, one persistence path; the only session-specific knowledge is the scope key.

Known Limitations

• A row dropped directly under another folder's last member files into that folder (the row above decides membership), matching project folders.
• Session folders have no Hide action; the hide preference is per project.

Follow-ups

• Repeated Pinned↔home transfers during one drag re-render the whole sidebar and leave ~25MB retained after GC on main as well; worth a look at the transfer path separately.
• The Sessions drop-to-unpin zone renders only when the section is expanded (or collapsed and empty), same as before; collapsed-with-rows keeps no zone.

Summary by cubic

Previously, dragging a sidebar folder collapsed its members and could leave the ghost offset from the cursor; now it keeps rows mounted and moves the folder as a unit, preventing layout shifts. Sessions tag groups previously could not be dragged and sessions dragged out snapped back; now they use the project folder DnD and persistence path, while an empty Pinned target stays out of flow.

Bug Fixes

• Removes the old drag spacer and instant-collapse workaround.
• Uses whole-unit collision bounds and translates each member row with its folder header.
• Keeps the zero-height "Drop to pin" target sticky at the scroller top.
• Caches unit rects once per pointer-move batch so folder drags don't recompute them per row.

New Features

• Builds Sessions as project-shaped children so folders and ungrouped sessions share rendering, selection, shortcuts, and DnD.
• Persists Sessions folder membership, order, and collapse state under SESSIONS_TAG_SCOPE; session drops update host tags.
• Validates Sessions folder rows through the shared tag-folder scope helpers, while keeping folder hiding project-scoped.

^{Written for commit 74926c6. Summary will update on new commits.}

📝 Walkthrough

Walkthrough

The Sessions lane now uses scoped folders and shared sidebar child structures. Projects and Sessions share expanded rendering and drag-and-drop behavior. Section dragging moves complete header-member units, and Sessions folder state persists through the unified container path.

Changes

Sessions sidebar data and scope

Layer / File(s)	Summary
Sessions scope, schema, and data construction apps/desktop/src/renderer/utils/workspaceTagFolders/*, apps/desktop/src/renderer/providers/CollectionsProvider/dashboardSidebarLocal/*, apps/desktop/src/renderer/routes/_authenticated/_dashboard/components/DashboardSidebar/hooks/useDashboardSidebarData/*, apps/desktop/src/renderer/routes/_authenticated/hooks/useDashboardSidebarState/*	Sessions workspaces now derive folders under SESSIONS_TAG_SCOPE. Sidebar data returns shared children and flattened workspaces. State lookup and deletion map the Sessions scope to a null lane project ID.
Sessions child integration and shortcuts apps/desktop/src/renderer/routes/_authenticated/_dashboard/components/DashboardSidebar/types.ts, apps/desktop/src/renderer/routes/_authenticated/_dashboard/components/DashboardSidebar/hooks/useDashboardSidebarShortcuts/*	The Sessions type uses project-style children. Shortcut locations include workspaces nested in Sessions sections.

Container drag-and-drop

Layer / File(s)	Summary
Section-unit sorting and collision detection apps/desktop/src/renderer/routes/_authenticated/_dashboard/components/DashboardSidebar/hooks/useSidebarDnd/sectionUnits.*	New utilities group section headers with members, calculate unit bounds, sort complete units, and detect collisions by unit centers. Tests cover grouping, transforms, and collision behavior.
Unified sidebar DnD state and persistence apps/desktop/src/renderer/routes/_authenticated/_dashboard/components/DashboardSidebar/hooks/useSidebarDnd/useSidebarDnd.ts, apps/desktop/src/renderer/routes/_authenticated/_dashboard/components/DashboardSidebar/providers/DashboardSidebarDndProvider/*	Sessions children participate in membership, sorting, section dragging, workspace drops, and unified persistence. The DnD context exposes container sorting strategies and the active section ID.

Sidebar rendering

Layer / File(s)	Summary
Shared project and Sessions content apps/desktop/src/renderer/routes/_authenticated/_dashboard/components/DashboardSidebar/components/DashboardSidebarProjectSection/*, apps/desktop/src/renderer/routes/_authenticated/_dashboard/components/DashboardSidebar/components/DashboardSidebarSessionsSection/*	Expanded content supports project and Sessions containers. Sessions uses the shared renderer and section callbacks. The old session tag-group component and section spacer were removed.
Drag placeholders and section actions apps/desktop/src/renderer/routes/_authenticated/_dashboard/components/DashboardSidebar/components/SortableSectionHeader/*, apps/desktop/src/renderer/routes/_authenticated/_dashboard/components/DashboardSidebar/components/SortableWorkspaceItem/*, apps/desktop/src/renderer/routes/_authenticated/_dashboard/components/DashboardSidebar/components/DashboardSidebarPinnedSection/*, apps/desktop/src/renderer/routes/_authenticated/_dashboard/components/DashboardSidebar/DashboardSidebar.tsx	Dragged headers and members remain visible as dimmed placeholders. Sessions folders do not expose hide actions. Empty pinned sections render a floating drop zone during workspace dragging.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to d85b6

The sidebar and Sessions drag changes are not ready to merge because section dragging can throw at runtime, while layout stability and Sessions bulk selection retain unresolved correctness risks.

apps/desktop/src/renderer/routes/_authenticated/_dashboard/components/DashboardSidebar/hooks/useSidebarDnd/sectionUnits.ts (1)

143-150: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Cache unitRects instead of rebuilding it for every row.

dnd-kit calls the strategy once per sortable item on each drag frame. This block rebuilds the union rect of every unit inside that call, so the work is O(units × rows) per item and O(rows²) per frame. With a sidebar of many workspace rows this runs on every pointer move.

Compute the union rects once per rects array and reuse them across items.

♻️ Proposed refactor

 	return ({
 		activeIndex,
 		activeNodeRect: fallbackActiveRect,
 		index,
 		rects,
 		overIndex,
 	}) => {
 		const activeUnit = unitIndexByItemIndex.get(activeIndex);
 		const overUnit = unitIndexByItemIndex.get(overIndex);
 		const unit = unitIndexByItemIndex.get(index);
 		if (activeUnit == null || overUnit == null || unit == null) return null;
 		if (!rects[index]) return null; // hidden / disabled row: nothing to move
 
-		const unitRects = units.map((u) =>
-			unionRect(
-				u.ids.map((id) => {
-					const itemIndex = indexById.get(id);
-					return itemIndex == null ? undefined : rects[itemIndex];
-				}),
-			),
-		);
+		const unitRects = getUnitRects(rects);

Add the cache alongside the other precomputed maps:

let cachedRects: ClientRect[] | undefined;
let cachedUnitRects: (ClientRect | null)[] = [];
const getUnitRects = (rects: (ClientRect | undefined)[]) => {
	if (rects === cachedRects) return cachedUnitRects;
	cachedRects = rects as ClientRect[];
	cachedUnitRects = units.map((u) =>
		unionRect(
			u.ids.map((id) => {
				const itemIndex = indexById.get(id);
				return itemIndex == null ? undefined : rects[itemIndex];
			}),
		),
	);
	return cachedUnitRects;
};

Capture emptyAtPickup with a ref or state.

onDragOver can update pinnedItems while activeType remains "workspace". The useMemo callback reads pinnedItems, but React does not guarantee that its cached value is retained. Recalculation can switch the section to the floating layout during the drag.

P2: When a session is bulk-selected, any subsequent project list or order update clears it because selectableWorkspaceIds still excludes all session rows. Add the session workspaces (including grouped rows) to the available-ID set now that Sessions uses the shared bulk-selectable lane.

Pre-existing: main's selectableWorkspaceIds also excluded session rows while the Sessions section already offered bulk selection with projectId: "sessions". Unchanged by this PR; noted as a follow-up.

This matches project folders, which also keep a derived folder header when its only members are pinned (the folder index derives from all host rows). Kept the parity; an empty-derived-folder filter for both lanes is a reasonable follow-up.

P2: When a user Ctrl/Shift-clicks a session row, the selection stores "sessions" as its project ID, but the outer bulk toolbar resolves selections only through the project list.

Pre-existing: the Sessions section passed projectId: "sessions" on main too, and its bulk actions come from the row context menu scope rather than the project toolbar. Not widened here.

Intentional. The float exists to keep the pickup itself shift-free; once the row transfers into Pinned, the in-flow section is what shows the row landing there, and the DragOverlay is unaffected by mid-drag layout. Keeping the float would leave the transferred row with nowhere to render. Measured A/B against main: the transfer path costs the same on both sides.

🌐 Web query:

For @dnd-kit/coreversion6.3.1, does DroppableContainersextendMap, and is getEnabled() the supported way to obtain an array of enabled droppable containers?

💡 Result:

Yes, for @dnd-kit/core version 6.3.1, DroppableContainers is a custom instance that extends the Map constructor [1][2]. It is explicitly designed to extend Map while providing additional helper methods [3]. Regarding the method to obtain enabled containers, yes, getEnabled is the supported and intended way to retrieve an array of enabled droppable containers [1][3]. This method is part of the API provided by the DroppableContainers instance to filter out disabled containers [4].

Use getEnabled() before mapping containers.

The CollisionDetection callback receives @dnd-kit/core 6.3.1’s DroppableContainers collection. It does not provide .map(), so section collision detection can throw here. Use droppableContainers.getEnabled().map(...) instead.

@Kitenite, the unit-rectangle cache and the ID lookup map are present in d85b66f38.

However, the current code still calls:

droppableContainers.map(...)

droppableContainers is not an array in @dnd-kit/core 6.3.1. The code must call droppableContainers.getEnabled() before .map(). The finding remains valid.
