I've been trying to do something relatively simple but that does not work.
I want to be able to collapse groups in sonata to enhance the user's experience.
->with('MyGroup', array('collapsed' => true))
-add('MyField')
->end();
This is based on the Sonata documentation.
Pretty simple but i can't see why it does not work. Does array('collapsed' => true) is not enough?
Is it an issue?
