how do we add submission approval routing workflow?

Also, what else can I do to make this form even better?

Hi,

I suggest you also checked this discussion thread

Please refer to our colleague Welvin's suggestion of Approval Workflow in the thread.

How about adding also a Preview Before Submit Widget at the end of your form. This way the end-user will have the option to review the answers before they will finally submit the form.

Hope this help. Let us know if you need further assistance.

Thanks.
