That's quite a list you have there! The database items you wish to add for the listings can be created using the custom form builder in Vantage, with the ability to add text fields, text areas, checkboxes, radio buttons, and select lists as you can see from the
Vantage admin demo. In terms of "Operational flow", the points specific to the theme:
2. Listings can be posted from the front end of Vantage, with admin users being able to also create listings from the WordPress admin dashboard. If you import listings in bulk, this can be done using the importer in .csv format.
3. You can select for listings to require approval before they are published.
4. If the information is available in the listing, then they can use the contact details there. There is currently no contact form built into the listing page at this time.
5. You can either allow registration on your Vantage site, or if it is disabled, then you would need to manually create accounts from the
wp-admin dashboard.
6. You can create listing plans however these are not subscription prices, so they are paying per listing. There are no receipt options built into the theme.
9. Search functionality can be previewed on the
Vantage demo site, with the refine results visible in the sidebar of the results page of a search
here.
If you have more questions, please feel free to post, however please make them relevant to the theme and what you actually want to know about the theme itself as this will allow us to give you a more detailed response. Thanks.
