You can try out DropdownExtendar of AjaxToolkit controls[^] : The displayed menu is merely another panel or control. Put a treeview there.

Other option is to have a user/custom control, combining textbox, image & treeview to have a feel of dropdown having a treeview.
Example here: Tree View in Dropdownlist[^]
