Skipping fields without validators

[missmatsuko]

I have a form that is split into several steps. When the user clicks a button to progress to the next step, I would like to validate all the fields on the current tab.

I thought I might be able to pass a selector for the step's div which contains multiple fields, but it seems I have to pass in the actual form elements (e.g. input, select).

So I thought I'd go through the form's elements, but I get this error when it hits a FormElement that doesn't have a validator. For example, a fieldset which contains other inputs.

Uncaught TypeError: Cannot read property 'validators' of undefined

Is there a way to skip validation for for things that are passed into validate() that don't have validators? Or is there a smarter way to achieve what I'm trying to do? Thanks!
