ComboBox Popup around Mouse Pointer


Hi All,

I'm looking to implement a specific bit of behaviuor,  and I was hoping someone could advise me how to do it.

When launching a ComboBox popup, the popup renders either above or below the ComboBox in question. When the box is located towards the bottom of the screen, and would otherwise be clipped, arrows are drawn at the top and bottom of the dropdown, and the ticked item is placed underneath the mouse pointer, and above the combo box that was clicked.

I want the latter behaviour to happen at all instances. When a box is clicked, the dropdown places the currently selected item directly underneath the mouse pointer. Is this possible? If so, how?

Thanks All
