  ->save();

Readonly options field renderer

By default options fields that are set to readonly via the locked collapse state only show selected options and hide other available options. That might not be what you want. Here is an alternative that turns this:

Into that:

Simply call $form->readonlyOptions('yourfield') in the ProcessPageEdit::buildForm hook or when using MagicPages in the editForm() method:

$wire->addHookAfter("ProcessPageEdit::buildForm", function($event) {
  $form = $event->return;
  $form->readonlyOptions('yourfield');
});
