Display Header Filter Icons
Set the headerFilter.visible property to true to display filter icons for all columns. To hide the filter icon for a specific column, disable that column’s allowHeaderFilter property.
Enable Search in Header Filters
Users can search for values in a header filter. To display the search bar, set the search.enabled property to true in the global headerFilter object or in a column’s headerFilter object. Use the search.mode property to specify the comparison type.
Change Available Filter Values
A header filter consists of unique values in its column. To change the filter values, group them with the groupInterval property or bind the data source to this header filter.
