Your eBay shop categories are completely dynamic and will change as you edit/delete them. As you add or remove categories they will change dynamically across all of your items (by default ‘Other Items’ will appear at the bottom of your eBay categories to catch any items that you don’t place specifically in a category. This is not an actual category like your properly named categories and it will not appear on your template, so don’t put any items into it. If you want an ‘All Items’ or ‘Everything Else’ category, then simply create one which is named accordingly).

When you first start using the new template and storefront, eBay regard you as a 'new' store and you may find any changes to categories take a few hours to show. This is not anything to do with the design we have installed, this is standard for eBay’s system to take longer to populate new stores (we guess they might be making manual checks on new shop owners). After a few days this normally speeds up to normal (and will take just a few minutes).

There is no facility within eBay to hide a category - you can either delete or rename.
