If the posts are stored and accessible by WordPress’ WP_Query then yes this is possible using just the shortcode. It might take a bit of work to achieve a view similar to the layout you have now.
If you still have an active support entitlement to the OpenDoor theme that you purchased then I suggest contacting them to find out whether the Car listings are compatible with this plugin. The OpenDoor author is welcome to contact me to discuss how the A-Z Listing plugin works and so that they and I can work together to try to get you rocking :-).
Unfortunately as the theme is paid I don’t have access to test things out in combination.
Thanks for reply
If I would pay you, could you help me fix this?
Hi,
The WordPress.org forum guidelines prohibit the discussion of jobs, payments, and direct access to other people’s sites. Therefore I cannot accept payment for helping you with this issue. I am willing to help as much as I can through these forums, though, without you paying a single penny 🙂
