Composer checklist¶

Quick routing when authoring a page:

Need	Use
Page identity	`GridViewHeader`
Entity facts (simple)	`GridViewEntity.facts`
Complex entity aside	`GridViewHeader.content` → `GridViewTemplate` id
Breadcrumbs	`GridViewNav`
Page-wide toolbar	`GridViewToolbar` at root, `target=None`
Table-bound toolbar	`GridViewToolbar` in `table-card`, `target=table_id`
Filters	`GridViewFilters` (`target=None` or scoped block id)
Search	`GridViewSearch` inside toolbar (one per table)
Commands / export	`GridViewActions`
Tabular data	`GridViewTable`
Dynamic columns	`GridViewTable.column_source`
Inline editing	`GridViewTable.edit` + `GridViewColumn.editable`
Custom cell	`GridViewColumn.renderer`
Column checklist filter	`GridViewColumn.filter` with `type="set"`
KPI / charts	`GridViewKpi`, `GridViewCharts`
Declarative form	`GridViewForm`
Bespoke wizard/UI	`GridViewTemplate`
Modal / drawer	`GridViewOverlay`
Placement	`GridViewLayout` + `GridViewArea`

Hard separation:
