# FxParameterFlags

These constants specify the characteristics of parameters display.

```
typealias FxParameterFlags = UInt32
```

## Discussion

Not all of the flags are 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), [`kFxParameterFlag_HIDDEN`](/documentation/professional_video_applications/kFxParameterFlag_HIDDEN), and [`kFxParameterFlag_DISABLED`](/documentation/professional_video_applications/kFxParameterFlag_DISABLED).

You are unable to give a group parameter a custom user interface.
