Webform Component with multiple fields I would like to make a custom module that integrates with webform (7.4).

I need to have a combo field which could be added to a form as one field but consists of 4 text areas.

I have found a discussion on this topic here -> http://drupal.org/node/965068 but first its confusing how he does it at the end he just says he figured it out, but also this is a solution for 6.3 and i need for the 7.4

Any help would be greatly appreciated.
You could use https://www.drupal.org/project/webform_addmore. 

A more flexible solution would be to use the Entityform module in combination with https://www.drupal.org/project/field_collection.
