The hidden-data macro hides the content that is in the macro when the page is being viewed, while allowing the content to be modified in the Edit view. This page shows the general form and provides an example.
The general form is:
{hidden-data:whenEmpty=Name|whenNoRows=Name|whenHasRows=Name}
Hidden content.
{hidden-data}
{hidden-data:whenEmpty=HiddenTextTest}
This whole section is hidden if the text below is blank.
{text-data:HiddenTextTest}{text-data}
{hidden-data}
