How to add or edit the fields inside a field group list.?
I am having an issue with field group lists.When I create a field group list in while configuring the view,I am able to edit the fields inside it.You can see the link to add more fields inside field group list,but when I edit its view (the table)in the section formed and realized there are more fields that needed to be added to this field group list, I no longer could edit or add fields to this field group list. Can anyone explain me the reason behind it?
