Tell us what you are trying to do? I am trying to easily add multiple photos to a custom post type withe the CRED Form. Super tool and I can add multiple photos but I need to select "Add File" for each photo. Is there any way the user can "Drag and Drop" or select multiple photos and have them all added?
Is there any documentation that you are following?
In the settings at the top of the form in the backend you'll find a setting to use the WP Media uploader, which offers drag and drop and enables selecting and uploading multiple images at once, I think that should suit your needs.
