Display Header Filter Icons
Assign true to the headerFilter.visible property to display header filter icons for all columns. To hide the icon for a specific column, set the column's allowHeaderFiltering property to false.
Enable Search UI Within Header Filters
The DevExtreme Grid includes a text-based search option. This feature allows users to search for specific values within a header filter. To configure the search panel, define the search property in the global headerFilter object or in a columns.headerFilter object.
The search panel's default behavior looks for values only within the same data field. You can include additional fields in the search. Specify the search.searchExpr property for this purpose. For example, this demo allows you to enter a state name in the City column's header filter. You can then see a list of all cities within the specified state and select city names that you want to use as a filter.
To apply a comparison operation used to search header filter values, specify the search.mode property.
