How do I get the Grid filter menu to appear?
The menu feature at the top of Grid naturally feeds in sub-categories of the parent categories you check off. For example, if you had a parent Beauty category, with sub-categories such as Hair, Makeup, and Skincare, those three sub-categories would appear at the top of the Grid layout when a reader clicked on your Beauty category.
In other words, for any parent category using the Grid layout, we recommend creating sub-categories for that category, if you want the tab menu to appear. This helps your users drill down into your past posts to find content that is especially relevant to them.
