Ability to specify behavior in Content by Label macro when pages are returned

Problem Definition

When using the Content by Label macro, when no data is returned, you are presented with the following panel:

There is no content with the specified labels.

For many users, this panel is large and visually unwieldy, as mentioned in CONFCLOUD-40839:

The macro Content By Label is cool, but I would appreciate an option how to disable the information "There is no content with the specified labels" if any document doesn't exist with specified label. It is really distracting and often useless info.

Suggested Solution

Provide the ability to determine how the macro should display when there is no data returned.
