filterbox UI calls filter method under the hood.

filter method can be called from anywhere i.e., by click of a button or any custom action.

In head filter, filter action is triggered automatically even when filterbox got one letter change , this is will send server many unnesessary requests. Can it be stopped? Then it can be trigger in need.

Filter dropdowm menu can be used for filtering.

There are buttons Ok and clear in the dropdown menu to initiate the filtering process. Filtering process is not initiated until any button is clicked.
