grid filter combo

Suite and Optimus Suite 5

Hello,

I need filter by combo for grid like this:
dhtmlx.com/docs/products/dhtmlxG … combo.html

But a book can have more then one Author.
I would like to have unique list of Authors in the combo filer and multiple Authors for a book.

E.g.

Filter combo:
John Grisham
Stephen King
Honore de Balzac

book1 - Authors:John Grisham
book2 - Authors:John Grisham,Stephen King
book3 - Authors:Stephen King,Honore de Balzac
book4 - Authors:John Grisham,Stephen King,Honore de Balzac

If ‘John Grisham’ is selected in the filter combo expected result will be:
book1
book2
book4

How can I do it?

Thanks a lot

Unfortunately such feature is not supported.
The only way is to create your own custom filter.
Here you can find a tutorial about the filter customization:
