Modifying Data Grid Column Search Widget

I have found the data grid column search widget from the following link, which is perfect for working . The only thing is it shows search window over each column.  Is it possible to make it show the search window for specific columns but not for all columns?

it seems you can’t, but you can modify any widget by
1- open the widgetName.mpk file
2- change the extension of the file to be like widgetName.ZIP
3- extract the widget file.
4- and you can change the widget XML and javascript as you want.
