Currently any user can see empty category either when there are some pages restricted for user's role or no pages at all.
This can be irritating and I propose to hide those categories which are empty for users who do not have Page Builder role.
In the example below there is a user with Supply Manager role who is not responsible for any Master Data related things - so there is no reason for him to add anything in Master Data category ever.

Will be good to have option to hide such cases.
