I'm trying to make pop-ups work the combobox without textElide and sizePolicy exapand (I'm using QSS)

Qt Code:
  1. qproperty-textElideMode: ElideNone;
  2. }
  3.  
  4. qproperty-vertSizePolicy: Expanding;
  5. }
To copy to clipboard, switch view to plain text mode 

but does not work, items from the QComboBox does not expand the size of the pop-up.

How to make pop-ups expand the size without affecting the combobox?
