How can I set the initial position of EditorGUILayout.Popup ?

Hi,

I'm using EditorGUILayout.Popup in a project and I have a problem with the position of the list of elements after a click on the control. The list used has submenus and is pretty big (takes the whole screen vertically). The problem is that I want to see the opened popup starting near the control position, but its start position depends on the current selected element, is there a way to workaround this behavior ?

Thanks for the help.
