[html-formfu] custom element with automatic constraint

[Steve Caldwell]

All,

Because I have so many instances of this in my code:

  - type: Select
    ...
    constraints:
      - type: AutoSet


I wanted to create a custom class that inherits from Element::Select and
automatically includes AutoSet as a constraint.  After poking around at
the documentation/code for a little bit, it's not immediately obvious to
me how to do this.  Has anyone tried this before, or have any advice on
where I could look?

Thanks,
Steve
