Padding and Spacing Specify various values for padding and spacing for the whole menu and for each separate submenu.
To create submenus you should choose the button at first. Let's add 6 subitems for the "Products" button for example. To add submenus you should click "Add submenu" button situated on the button builder Toolbar once.
You'll see that the "Products" button has 1 subitem now.
To add more subitems click "Add item" button on the Tollbar. The "Products" button has 5 subitems now.
To add the next level of subitems click "Add submenu" button once and then click "Add item" button.
