Your collection landing page, such as Pool Cabins or Dog-Friendly, shows every property instead of only the matching ones.
Why this happens. The property explorer shortcode shows all published properties unless you give it a preset filter.
How to fix it. Add filter attributes to the shortcode on each collection page, using the slugs of your amenities or tags. You can find those slugs in WordPress admin under Properties, then Amenities or Tags.
Filter by amenity. [hfsync-explorer amenity=private-pool] shows properties that have that amenity. Comma-separate several slugs to require all of them, or use amenity__or=slug1,slug2 to match any of them.
Filter by tag. [hfsync-explorer tag=dog-friendly] filters by a property tag. Tags synced from your PMS appear among these tags.
Filter by bedrooms. [hfsync-explorer bedrooms=5] shows properties with five or more bedrooms.
Other attributes. Other supported attributes include type, group, location, city, state, bathrooms, pets=yes, featured=1, and exclude.
Keep attribute values unquoted when the shortcode sits inside a page-builder element.
If an amenity applies to every property in your portfolio, filtering by it still returns the full list. This is the expected behavior.
