I understand what you need, but right now we don’t have a shortcode or a page template to combine 1 category + 1 city.
We’re thinking about adding a shortcode, but I’m not sure when it will be launched.
Meanwhile, you can use the shortcode by ID to group together properties in a list as you like
Or you can use the taxonomy pages created by WordPress
This will give you a page with ALL Houses, ALL Offices and so on.
Same applies for City, Area, Action taxonomy URLs. You can list ALL listings from a certain city using such links.
From here you take the links listings by CITY
These links can be added to the menu automatically, from here http://www.nadlan-il.co.il/wp-admin/nav-menus.php
I enabled the categories/actions/areas and cities list to show, so it’s easy just to drag and drop to the menu.
Hope it helps.
