Phoenix Form.inputs_for prepend options
I am trying to use the :append option of inputs_for/4.
The reason I would like to use that option is to render an empty (disabled) fieldset to be used as a template (I have an add button that should clone and add the fieldset).
The problem is that the append option only works if no parameters were sent through the form, which means that I lose my template if I got validation errors.
Any idea on how to solve that?
Thank you

Add it to the dataset so inputs_for renders it automatically and filter it out in handle event?
