Edit submitted content
You can edit the submitted content via dashboard if you are a admin.
If you are a regular visitor and wanted to edit the submitted post then use shortcode [upg-edit] on a page. Don't forget to select that edit page in your UPG settings.
To use edit form for specific layout
This will use 'simple layout' as it's edit form.
To enable ajax
Ajax will not work in edit form. It is build only for submission form.
Note: Edit layout will may not work as expected for all layouts. You need to create your own in personal edit layout.
