I want to be a marquee drop-down menu, it should choose the combo box, but I have a combo box displays text style is on the left, and right is like spin box with two arrows up and down, and my style of the font combo box as much as I expected, is on the left shows a down arrow to the right, but when I am using qt designer to edit them, right-click on the combo box after the "edit item" option on the menu, can add options into it, and right-click menu after I created the font combo box without "edit item" option, this is a what circumstance?

Use combo box, and then set it to editable, leads to a combo box displays text style is on the left side, right side is the arrow,
