By default all form submissions are stored and can be accessed from within the forms section of the website, from the list of forms hover and click on the submissions action, or when on the edit screen click on the “Submissions” menu item.
You can manage the columns displayed in the submission table by adding a plugin filter to your themes functions file, a way to do this visually will be coming soon.
You should see a paginated list of form submissions, which is searchable via the search entries input above.
All new entries are highlighted with an unread label next to the entry id.
To view an entry in more detail click on the entry id, or hover over it and click on the view action.
On the left hand side is a list of all the information submitted, and on the right hand side is information about the submission such as the date/time and the user account / guest who submitted it.
