Pull request overview
This pull request updates the TreeView ItemSelectionAndCustomization demo to showcase the new disabledNodeSelectionMode option. The option controls how disabled nodes behave during selection operations and supports two modes: 'never' (disabled nodes cannot be selected) and 'recursiveAndAll' (disabled nodes can be selected recursively or via select all). The demo adds one disabled node (Samantha Bright, COO) to demonstrate this feature across all framework implementations.
Changes:
- Added "Disabled Node Selection Mode" selector to demo UI across all frameworks
- Set the
disabled: trueproperty on the "Samantha Bright" node in all data files - Updated type definitions to include the
disabledproperty in Employee types - Added "Updated" badge to the demo in menuMeta.json
