If menu items are showing as unavailable (greyed out) on your storefront, check these causes:

Someone may have toggled the item off. Check in the dashboard Menu page — look for items with the toggle switched off. You can also check the merchant app's Menu tab where staff can quickly toggle items.

The product or category may have a time-based availability window. For example, a breakfast item set to be available from 7am-11am will be unavailable outside those hours. Check the product's availability settings in the menu editor.

Products must be in a category, and categories must be in a menu. If the category is orphaned (not linked to any menu), its products will not show on the storefront.

A product without a base price or any size variants will not appear properly on the storefront. Make sure every product has at least a base price or one size variant with a price.
