When you click on the Menus Module you'll see a list of menus set up for your restaurant. 

These menus have been determined by the site and menu structure when your account was setup. Each restaurant may have different menus customized for you. 

Typically you'll see a Lunch, Dinner, Kid's Menu, Happy Hour menu, etc. 

Menu Sections allow you to have sections within each menu. For example, the Lunch menu may have an Appetizer, Sandwiches, or Salads section. You may add, delete, edit and sort the sections within a specific menu. 

To sort the sections within a menu click the up or down arrow in the section to re-organize the sections.

To edit the menu items click on the edit icon for each section. This will take you to the menu items of each section.
