The Extras list shows one card per extra with its price, an Active/Inactive badge, rating and description. Use the Search box, the sort dropdown (Sort Alphabetically A-Z / Z-A, Sort by Price Low-High / High-Low), the Product Categories checkboxes and Show Inactive Extras in the left filter. Inactive extras are hidden until you tick that box. To hide an extra from customers, open it and turn Is Active? off - there is no delete.
