How the shortcode works:
Add the shortcode in your page.
Specify the IDs of the elements you wish to show in the shortcode. The IDs are taken from the list
This shortcode can be used in different ways. Type 2 design works better with 1 property per shortcode and you can use visual composer row / column options to make elements show in different design variations.
Type 1 design looks good if you add more categories in the same shortcode
To have an image for the city/area you add in the shortcode and a text description, follow these steps.
Edit the category and add the Featured Image and the description.
