You can easily remove menu items and add new links using the menu editor in SPP Settings > Menus.
To add a custom menu item with an icon you will need to include the icon’s HTML code in link text, for example:
<span class="glyphicon glyphicon-shopping-cart"></span> Packages
To get the full list of available icons and their codes visit Bootstrap icons.
Tip: if you make a mistake, you can restore default menus by clicking the Reset link at the bottom of the menu editor.
