Underscore Rules
Number underscore symbols ( _ ) before name of each menu item will identify for their sub level.
Menu items have no underscore symbol will be the top level menu items (level 0). All menu items with 1 underscore symbol (level 1) staying under a level 0 menu will become its sub menu items, and so on.
Mega Menu
You can also input [mega] at beginning of a level 0 menu name to make it become a mega menu. If URL of a mega menu is a label URL (/search/label/name_of_label), it will become mega content.
Menu Icons
You can add icon to menu item name by using FontAwsome codes. Example:
Pages or Link List widget?
Which is better? Both have their own advantage and weakness.
If you use Pages widget, you can drag and drop position of menu items and can add page URLs to menu list very easily, but you can not edit custom links. You must delete an menu item and add another one if you want to edit it.
If you use Link List widget, you must spend time to use arrow buttons to move menu items up / down to their desire position, this is the weakness. But you can edit any menu item (both name and URL) very easily.
If you don’t want to use the default menu widget that template author set up for you, you can remove it and add another one as you like.
