You applied the following condition to the paging button in the showcase User Management Dashboard:

class="btn {{Users.link.prev.default( "disabled" )}}"

How did you do this? By hand coding? Is there any description of the code?

There is other code like this:
{{Status.contains( "Active" ).then( "label label-success", "" )}}

I can't find this in the documentation or did I miss something?

Hello,
