Forms can be used to edit existing items in a story, allowing users who have edit or higher permissions on the story to contribute and collaborate on the story easily. There are a few pieces of information that you need to be aware of to be able to fully harness the power of using forms to edit items.
The forms must be set to Allow Item Editing. This setting can be found in the “Manage Forms” Dialog box as shown below. If this option is not selected, that form can only be used to create items and not edit existing items.
When using the form via the Forms slide-out panel (click Forms on the right-hand menu), you can select items in context on the view and edit them easily as shown below.
When an item is selected, the name of the item will appear above the available form names. The form will also populate with the current values those attributes hold, just as shown in the image above.
This makes editing a specific set of attributes defined by the story owner a lot easier for the editors and admins. This gives control to the owner to ask for collaboration on key attributes and information, but also allows admins and editors to easily change the attribute data.
When the form is accessed via the URL or QR code, there will be two options, to either create a new item or edit an existing item, where a drop-down list of existing items will be presented to choose from. This can be seen in the example below:
