I need to change the add item layout to display in the main site and not using lightbox.

 

I've deleted class="modal" and the rel attribute, now it open in the same page but it override my entire site deleting the structure (no body or divs and so on) so it open in a empty page with the form.

 

How can i embed the add item form in a choosed div?

Same problem. Anyone fix this please?
