Enterprise users can use this feature to hide irrelevant Report Groups and prevent their list from becoming cluttered.
To hide Report Groups from your list:
1. Go to the Designer and open the Report Groups section
2. Hover your cursor over the name of the report group that you'd like to hide, and click the 'Hide' icon that pops up.
This will move that group to the 'Hidden' folder so it will no longer show in your main report group list.
You can always click "Show Hidden" to view hidden report groups and bring them back into your main list as needed.
Note: Hidden groups are specific to each user in your company, so the groups that you choose to hide will only be hidden for you. Others can choose to hide different groups as needed. You can also rearrange this list and it will only affect your personal account.
Hope this helps! Let us know if you have any questions!
