How to completely customize a custom post type listing

What are you trying to “overhaul”? Most customization to a CPT specific detail page can be achieved with CSS, creating and positioning of custom fields, hooks etc.
Changing the template itself will change it for all other CPTs too.

If you can be more specific, we can point you in the right direction.

I don’t really need an “author/owner” section for these pages
Hide those sections with CSS on those pages. Each CPT has its own class assigned to the body tag. See image.

The various info displayed is controlled by the custom fields for a particular CPT, let’s say the Breed CPT.
You can change the order by dragging up and down at GD > Breed Settings.
You have a setting in the custom fields to add it in the sidebar, or an existing tab or create a new tab.

If you need us to give you some CSS or have a look at your site to assist, post your URL and WP admin details in a private reply and we will get you started.

1. You can add any information you like to the “Profile” tab, by entering it into the main description of the listing.

2. To add any custom fields in a new tab you create yourself, see https://wpgeodirectory.com/docs/core-place-settings/#fieldset
You need to create a fieldset, and then put the custom fields below that fieldset.

Select “Details page own tab” for where you want to show the fields
Details page own tab: Selecting this for a fieldset will create a new tab, selecting this for a custom field will show the custom field under the fieldset with the same setting above it

Thanks
