Admin shouldn't render label tags on hidden fields

[Michael Newman]

If a field in the admin is hidden, the label tag is still rendered. It would be pretty easy to not have that happen anymore. See patch attached.

Simple check to is_hidden to determine if we should render the label.

See also the patch attached to #7859.

The patch is not ideal. With that patch, if the row contains just one field and that field is hidden, then you're left with an empty <div class="form-row title">. The patch should be improved to not display the row at all in this case.

This is effectively a dupe of #11277.

Aloha,

I use the following snippet as fieldset.html.

It not only hides the input field instead if the fieldset contains only a single element which input-type is set to hidden it also hides the surrounding div-elements. So no space is wasted.

The snippet inserts the style-attribute with display: none. Others may prefer to insert a css class. But this way no one has to edit the admins css.

Maybe someone could test if this solution has side effects in other cases.

Regards, lacki
