Every store has menu Items and Sizes for each offering on the menu. Each Item Size for each store is completely configurable independent of the other store's settings for the same Item Size. When first creating the Item Sizes many similarities are populated to all the stores, but they can still be set independently. Make sure that you have Admin open to the correct store, to view, add, or edit Item Sizes.

The Navigation List has many sections. Clicking on a section will open a window with the search and other options available in that section. For the Items section users can search by Item Name or Category. Select the “Search by:” choice desired, then enter the characters for the search into the “Search Data:” form field, [covered up in this image] and then click the Search button. Because there are only a couple hundred items, users can merely click the Search button, and a list of all Items will appear. The Items will have settings and availability of the item for the store selected.

For the Items section there is also a New Item button and a Configure Item Categories button.
