I'm trying to implement my own drop down with custom controls on it, but cannot find proper control to that. In fact I would like achieve exactly the same result as Kendo Grid filter window. On on some button press it drop downs a popup (window) which automatically close if clicked outside the window, but allows usage, normal drop down list, multiselect, datepickers inside. So exactly what grid filter does. However I cannot find proper control to achieve that.
Could you advice?
