I just renamed “Places” to “Attractions”, rather than deleting the “Places” post type. All works fine.
I really would like the possibility for a visitor to tick the different post types from the ribbon below the map, similarly to ticking the categories in the filter box.
(and also be able to order the custom post types, or at least have them ordered alphabetically, instead of by latest – but maybe I can change the date or order in PHPmyAdmin?)
Regarding the performance issues: if I have 1 post type, 20 categories with 50 listings each, all the 1000 listings will show on the map. But if I have 10 custom type posts, 10 categories for each post type, and 10 listings for each category, then showing the 1000 listings would be a performance issue?
Would allowing a visitor to choose multiple post types from the ribbon, rather than only one at the time, still be a problem?
PS: superb work guys; just wanting to give kudos so you are not getting too sick of all your high maintenance customers 🙂 🙂
