Selecting all values

This option allows you to ensure that all data may be examined at once in a dashboard filter. For example, in single select mode on a cereal name filter, you can only look at details of one cereal. It may be interesting to look at information of all cereals at the same time.

You have added a filter widget to your dashboard.
  1. Open the dashboard in Edit mode.
  2. Hover over the filter and click .
    The Settings modal window appears.
  3. Click the Display Settings tab, then check the Allow only one item to be selected at a time option and the Include an option for '(All)' sub-option.
  4. Click APPLY.
The All option appears in the filter box.
