Show/Hide Category Selector
When adding categories in your store, a Categories Selector will be added to the storefront by default. The Category Selector displays on the left side of the storefront so the customer can easily see the different product groupings. Each category name is also clickable so that the customers can quickly navigate to the category of their choosing. This is great if you have a store with multiple/many categories.
However, if you ever want to hide this feature, you can. To do so, go to the Categories page inside of your store and unclick the Show categories selector. The Categories Selector will then be removed from the storefront.
