Pull request overview
Updates the TreeView “Item Selection & Customization” demo documentation to better describe selection options and align framework-specific template/customization APIs.
Changes:
- Rewrote the main demo description to cover selection configuration options and programmatic selection APIs more comprehensively.
- Added React and ReactJs-specific
description.mdfiles to referenceitemRender(instead of the coreitemTemplate) for node customization.

- The sentence "Users can click nodes or item checkboxes to select." is grammatically incomplete (missing the object). Consider rephrasing (e.g., end with "to select them" / "to select items").
DevExtreme [TreeView](/Documentation/Guide/UI_Components/TreeView/Overview/) ships with configurable selection functionality. Users can click nodes or item checkboxes to select. This demo allows you to modify selection behavior using controls below the TreeView. A DevExtreme [List](/Documentation/Guide/UI_Components/List/Overview/) on the right of the TreeView displays selected items in a flat (non-hierarchical) list.
