  • Just to clarify, you want the form elements to be unloaded by default, and then loaded in via ajax if required.

  • maybe in edit of node should be loaded and in uncheck hide them(remove)

  • According to the FAPI docs fieldsets can't have #ajax set on them so my guess is you'll need to do this manully

  • @Clive hi Clive,Thanks for your attention. I know I have to do it in form_alter, but I have some idea how can I perform it,maybe get groups in form $from['#groups'] and foreach of them disable sub fields or some thing like this. you have better idea?

Have you take a look at conditionals fields, works great for node-form and can help you to build your own code.

If you want a programatic replacement for conditional fields, then you are looking for the #states attribute in the form api. https://api.drupal.org/api/drupal/developer!topics!forms_api_reference.html/7#states Add that in a form_alter and it does the ajax for you.
