The available sizes of a product size group relation can be indicated in the menu item list rather than just in the product page.
Displaying all available sizes of an item on item list provides straight up information to the app user about other available sizes of the same product without selecting the item. Sizes of a item will only be displayed in item list when menu is configured to use size group name and the 'Generic name' is configured in the size group relation
1. Refer articles Apply Size Group and Product Size Groups to create product with size groups and configure 'Generic Name'.
2. Navigate to Web Ordering > Menus > Edit the menu, switch to 'Settings' view. Enable the flag 'Use Size Group Names for Menu Items' under 'Menu Settings' and save menu.
3. The available sizes are displayed in the item list as shown below. Default abbreviations are used for some standard sizes. Abbreviations for sizes can also be configured on the size groups. When no default or configured abbreviations are available, the size name is displayed.
Note: Available sizes for an item are displayed in app menu item list. If one of the hidden size product is out of stock, all the available sizes are still displayed
