TYPO3 Core

If I define Categories that have no settings those should be hidden:

categories:

    label: 'Blog Example 2: Noting here'

    label: 'Blog Example'
  BlogExample.empty:
    label: 'Empty: Nothing here'

  BlogExample.templates:
    label: 'Templates'
    parent: BlogExample
  BlogExample.pages:
    label: 'Pages'
    parent: BlogExample
  BlogExample.settings:

    parent: BlogExample
