# #10134 [Bug 646487] Composite layout: focus fix, body-layout gating, and setup UI

> Multiple bugs in composite layout management are fixed, including focus handling, multi-select deletion, configuration key conflicts, and layout subtype restrictions. UI labels are clarified and a Details FactBox replaces the Theme and Header/Footer Box.

[Pull request](https://github.com/microsoft/BCApps/pull/10134) · merged into `main` (BC30) on 2026-08-21 by v-mortenr · 10 files (+1484 -159), 9 AL · fix · tier official · reviewed (checked by Opus)

## What changed

- Focus now moves to the newly created theme or header/footer part
- Multi-select delete now removes all selected parts and skips out-of-box parts
- Configuration rows are keyed by the composite layout reference and created with a complete key, so they no longer collide or get rejected
- Theme and header/footer assignment is limited to body layouts in the UI
- A new Details FactBox replaces the Theme and Header/Footer Box, and the configuration page explains each row's scope in words
- Behaviour changes for users or extensions.
