Summary:
Additional form template values: has_required_fields & required_symbol
Detailed Description:
It would be handy to have a form template value that can flag if the form has
any required fields.
This would allow us to optionally display a message lik '* marked requires
fields' if there are required fields in the form. Otherwise, the message can be
hidden if not relevant.
A global required_symbol field would be useful too.
We could use these values like so:
{if $has_required_fields}
<p>{$required_symbol} marks required fields.</p>
{/if}
Cheers!
