Create a self-referencing ref on the subject, set parent_col_id on the foreign-key column pointing to the primary key column, then set tree_type to hierarchical and choose tree_display_col_id on the tab row. Finally place a Tree view leaf panel on an existing screen type.

Create a task for the business operation, add a drag_drop row linking source table, target table, and task, then map columns to task parameters in drag_drop_parmtr. Enable only the valid variant combinations in drag_drop_matrix, since all combinations start disabled.

Groups use form_field_in_next_grp with a label and render as sub-headings within one section, while sections use field_on_next_tab and render as separate collapsible blocks. Use groups for related fields in one concept and sections for genuinely independent concepts.

The task_setup_tab_variant_tree_overview task creates the variant rows but does not populate parent_col_id. You must set it explicitly on the identity/PK column's row pointing at the FK column, which is the reverse direction from the base table's col.parent_col_id.

The conditional_layout entity only has apply_to_grid, apply_to_form, apply_to_edit, and apply_to_scheduler_resource flags; there is no apply_to_card_list or apply_to_tree. Verify empirically whether formatting appears on those components before relying on it.

Set auto_resize_grid_col to no once a table or variant reaches roughly 20 or more visible columns, per documented performance guidance. Auto width measurement becomes expensive on wide or high-volume grids, so measure rather than guess.
