Combo in datatable

Hello

I am using combo control in datatable of my application. Behavior of combo box is to open up list/content on single click of cell. Requirement is to open content of combo only on clicking on any icon i.e. Dropdown icon/list icon of combo. And it should immediately close it if clicked anywhere else other than cell.

Is there any way around it ?
Also it should delete/clear selected value in cell on clicking of cross icon of cell.

There is no way to reconfigure the default combo behavior, but you can create your own editor based on the existing combo editor.
