JavaScript/jQuery FilterBuilder API

The FilterBuilder widget allows a user to build complex filter expressions with an unlimited number of filter conditions, combined by logical operations using the UI.

import FilterBuilder from "devextreme/ui/filter_builder"

Type:

Object

DevExtreme widgets are integrated with many popular libraries and frameworks. See the Installation section (for JavaScript libraries) or the Prerequisites and Installation section (for ASP.NET MVC framework) to find details on setting up DevExtreme with a particular library or framework.

The following code shows how to create the FilterBuilder widget using every supported library and framework. For more details on working with widgets in these libraries and frameworks, see the Widget Basics topic for jQuery, Angular, AngularJS, Knockout or ASP.NET MVC.
