feat(spec+showcase): add 'tree' view type + business_unit org-chart example - #2184
Merged
Conversation
…' view type Adds the 'tree' visualization type to the spec ListView schema (enum + a TreeConfigSchema for parentField/labelField/fields/defaultExpandedDepth) so a self-referencing object can be served as a tree-grid, and exercises it in the showcase with a new showcase_business_unit object (self-referencing parent), a 3-level org-chart seed, an 'Organization Chart' tree view, and sidebar nav. Pairs with objectui plugin-tree (renderer). Refs objectui#1885 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

sys_business_unit is already a self-referencing hierarchy (parent_business_unit_id, ADR-0057 D2) with BFS graph traversal, but Setup only exposed flat grids. Adds an `org_chart` list view (type: 'tree') that renders the hierarchy as an indented, expand/collapse tree-grid, listed first so it's the default tab. No schema change — only surfaces the existing parent pointer. The active/inactive/by_kind/all grids stay for search, filter, and bulk edit. Uses the 'tree' view type added in #2184; renderer is objectui plugin-tree.

What
Adds a
treeview type to the@objectstack/specListView schema and exercises it in the showcase with a self-referencingbusiness_unitorg chart.This is the metadata/data half of the tree-grid feature; the renderer lives in objectui (plugin-tree). Pairs with objectui#1885.
Why
Self-referencing, arbitrary-depth hierarchies (org charts, category trees, BOMs, nested comments) can't be expressed by fixed-depth
grouping. A tree view nests records by a single-parent pointer field. ObjectStack'stree/lookup self-reference is unambiguous (unlike Airtable's many-to-many links), so the nesting is well-defined.Changes
Spec (
packages/spec/src/ui/view.zod.ts)'tree'added toVisualizationTypeSchemaand theListView.typeenum.TreeConfigSchema(parentField/labelField/fields/defaultExpandedDepth, passthrough) +treekey onListViewSchema. Without this the runtime Zod-validates view metadata and silently dropstype:'tree'.Showcase (
