This is a good idea, but the form's fields could simply be reduced using existing theme (and supported plugins) hooks. Besides, a simply jquery extension could achieve this using a child theme.

first, RTFM for the jquery extension of choice,

second, implement example for your DOM structure.

third, enqueue relevant js and css files in child theme's functions.php

I need this ASAP! The current two part process is not only clumsy, but very unprofessional.

I totally agree on this one too! The current submission page kills the traffic I'm bringing on the page. People need to see their progress while submitting their details.

I think its a must have for the Bookable listing form (WooCommerce Product) to be integrated into the Listing Submission form. Currently its two separate forms and very confusing.

I really like the form that these guys have done. It looks sharp. Just my 2 cents. - https://dribbble.com/shots/2851692-CRM-Onboarding/attachments/587135

Add listing submission form is the only part of Listify theme that is looking unprofessional. Everything else is professionally design. Modifying it, like Mr. David Patrick suggested will add more perfection to theme and satisfaction to the customers. Thank you Listify Team, you are doing a great Job already.

This is one of the greatest ideas suggested so far, Because the submission form is the only thing that does not look professional.

This would really, really improves the UX of the form. Great idea!

This would be a very nice feature to have on the theme. Currently, it's very lengthy page.

And additionally, a progress bar to show how many steps completed will be a great add-on!

1 form is simpler and it's already short compared to other fillin forms :) Maybe add collapsible menu for step 1, step 2, etc. and admin can decide which menu to collapse. This will make the form appear shorter.
