Note that the suggest popup is not a child element of the combobox’s root, it’s separately placed in the overlays div at the document root. Check with e.g. Chrome’s Inspector to see.
Then, how I can override the suggest popup style only for combobox with my style “tree-shooser” ?
I need to put :
display : none;
but I just want hide the suggest popup for my specific combobox, not all.
