The navigation bar allows customers to find the category they want clearly and quickly, and sellers can add the important content they want to express in the navigation, just like a physical store has daily necessities here, a food area there and a promotion on the other side, as shown below:

If the customer clicks on the early education toy, all toys belonging to the early education toy category in the store will be displayed, and clicking on the store dynamics will display the latest trends of the store!

My humble opinion, hope to adopt it!
