Custom Fields Add On

Hi, by default the Custom Fields extension allows adding the fields to
1. [adverts_add] form.
2. [adverts_list] search bar.
3. The contact form on Ad details page.

If you add fields to the [adverts_add] form and user will fill this fields when creating an Ad then on Ad details pages these fields can be automatically shown.

On the Ad details pages (like https://demo.wpadverts.com/lite/advert/rayman-legends/), it will be displayed below location.
