Hi,
Attached is a patch to add a small function to z3c.multiform. The
function is called 'hasChildrenAndAllSubFormsDisplayMode' and is useful
as a condition for an action.
The use case is this: There is a 'remove' button that deletes lines from
a multiform form. I don't want this button to show in my form unless the
container has children.
I hope is useful enough to get in.
Best Regards,
Lorenzo
