Property Value

Type	Default	Description
Boolean	true

true to allow field selection; otherwise, false.

Remarks

The <DxFilterBuilder> component allows users to select fields with mouse clicks, tap gestures, and keyboard shortcuts. To disable selection for a specific field, set its AllowSelection property to false.

The following code snippet disables selection for the Supplier field. Users cannot build a filter condition with this field, but can expand or collapse it in the tree.
