Grouping certain tag groups as search tag menus create a more folder-like structure, making it easier to search in the Asset Manager and Create and Publish module.
There are multiple ways to search through, for instance, the Asset manager with filters, the search bar, and suggested tags. One other way to do it is to pin certain tag groups as a search tag menu. This can be done in settings in Settings. This search tag menu will show up as a dropdown list with a maximum of eight tag groups in your Asset manager.
This resembles more a folder-like structure that can be more recognizable when users are coming from a previous situation where Assets were stored in a folder structure.
The order of the categories can be changed in settings to determine how they show up in the Asset manager.
