Note: These options require the Secondary Navigation add-on in GP Premium.
We can adjust the width and height of our menu items, as well as the height of our sub-menu items in Customize > Layout > Secondary Navigation.
Width
This option adds the value to the left and right of your menu item item text. 20 = 20px on either side of your text.
Height
This value determines the height of your menu items. 60 = 60px tall.
Sub-Menu Item Height
This value determines the height of your sub-menu items. 10 = 10px on top and bottom of the text.
