Header Filter
A header filter allows a user to filter field values by including or excluding them from the applied filter. Click a header filter icon in the field chooser or on the field panel to open a popup menu that displays all unique field values.
Use the following options to configure the header filter:
-
allowSearch
Enables a user to search through field values. -
showRelevantValues
Specifies whether to show all field values or only those that satisfy the other applied filters.
In this demo, a filter is applied to the Country field. This filter includes only the United Kingdom. The City field displays only cities in this country because the showRelevantValues option is true. If you clear the corresponding checkbox under the widget, the City field displays all cities, regardless of the other applied filters.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
Thank you!
