Skip hidden fields on Phoenix inputs_for

I just found out that Phoenix Component inputs_for accepts a skip_hidden attr which was very useful today. We have a has_many relationship that we are using <.inputs_for> to decompose the nested fields and as it was generating some hidden fields the style was breaking.

We are actually using a Tailwind divide on the parent tag and those hidden fields were adding extra separation borders. A way to solve that was calling <.inputs_for twice as this:

<div>

  <.inputs_for field={@form[:posts]} />

  <div class="divide-y">
    <.inputs_for :let={form} field={@form[:posts]} skip_hidden>
      <.input type="text" field={form[:title]} label="Title" />
    </.inputs_for>
  </div>
</div>
