How to group two fields while creating content type? I wanted to a content type which get number of title and links. And I want an option which allows the user to add more title and links. The fields in the content type are

   1. Promotional Image
   2. Image Alternative Text
   3. Title
   4. Links


In the above mentioned field. I wanted to group only the Title and Links field. I wanted to give add more option for those two fields alone. Can anyone tell me how this could be done. I cant establish a link between those two fields. At present when I select the 'number of values' option in field settings it gives me add more button to each field but I am not able to link those two fields with any relation. Can anyone please suggest me a solution?
If you want to group fields together to be accessible as a single field on your form, the easiest way is using the Field Collection module. It:


  Provides a field-collection field, to which any number of fields can be attached.


Using that you can group your Title and Links fields into one, and you'll have an 'Add more' button for the group, rather than for each individual field widget.
