```

## Discussion

This flag is only valid for parameters that also set [`kFxParameterFlag_CUSTOM_UI`](/documentation/professional_video_applications/kFxParameterFlag_CUSTOM_UI). Of course, not all of the flags apply meaningfully to all of the parameter types. The only flags, for example, that apply to Group parameters are [`kFxParameterFlag_COLLAPSED`](/documentation/professional_video_applications/kFxParameterFlag_COLLAPSED), [`kFxParameterFlag_DONT_DISPLAY_IN_DASHBOARD`](/documentation/professional_video_applications/kFxParameterFlag_DONT_DISPLAY_IN_DASHBOARD), `HIDDEN`, and `DISABLED`. You can’t give a group parameter a custom UI.
