Pull request overview
Adds a new “Search in Embedded Components” documentation section for DropDownBox, describing how to implement search when embedding DataGrid (flat data) or TreeList (lookup display-value search). It also modernizes parts of the existing “Synchronize with the Embedded Element” topic code samples.
Changes:
- Added an overview article explaining shared configuration and the differences between DataGrid (
searchValue/searchExpr) and TreeList (lookup-drivenfilter) search approaches. - Added two new how-to topics: one for embedded DataGrid search and one for embedded TreeList search (lookup scenario).
- Updated the existing synchronization topic’s wording and refreshed Angular/Vue/React code samples.

| [note] This implementation strategies support single selection only. To implement multiple selection, use the [TagBox](/api-reference/10%20UI%20Components/dxTagBox '/Documentation/ApiReference/UI_Components/dxTagBox/') component instead. |
