How can I customize the drawer menu to cover also the header? I have tried many codes from previous discussion posts but most of them will cover also the close drawer button.
If it is easier, I am also comfortable with having the header to become white when the drawer opens.
However, I saw that when I close down the drawer menu, the header turns transparent before the drawer closes - leaving an unpleasant visual. Is it possible to add a transformation time to the header changing color?
