attachViewportTo to cell of layout

Hello DHTMLX SUPPORT,

I am using dhtmlxlayout with 2U pattern, i attach toolbar and grid object in cells(“a”). At toolbar object i have a button item tittled “add row” when clicked will create windows object that has a form object in it which is used to add new row to grid.

My question is how to use attachViewportTo() method of windows object only in cell(“a”).

Thank you.
