The FWRE Extra Fields addon adds a structured amenities checklist to the property form. Agents can tick which features a property has, and those selections appear as a Features block on the public property detail page.
When the addon is active, each property gains an Amenities checklist in the edit form. Options in that checklist come from FW Real Estate → Dictionaries → Amenities, where you can add, remove, or rename entries (Pool, Garage, Balcony, Air Conditioning, and so on).
Selected amenities are also available as search filter values when you configure the Search module, so visitors can filter listings by specific features.
Open any property for editing and scroll to the Features / Amenities field. Check every amenity that applies to the property and save. Unchecked amenities are treated as absent.

Checked amenities appear in a Features block on the single property page, displayed with icons or checkmarks depending on your active template. How absent amenities are handled is controlled by the Features display setting.

Go to FW Real Estate → Settings → Addons tab → Extra Fields to configure the addon.

An additional setting is injected into Settings → General tab → Localization by this addon:
The list of available amenities is maintained in FW Real Estate → Dictionaries → Amenities. Add a new entry there to make it appear in every property's checklist. Removing an entry from the dictionary removes it from the form and from all frontend displays.
Extra Fields handles structured amenity data through the fixed checklist described above. For fully custom field types (text, number, dropdown, and others) added on a per-property basis, see the Custom Fields addon. Both addons can be active at the same time.
To install this addon, open the Add-ons panel inside FW Real Estate. See Getting Started → Add-ons for details on free addons, paid addons, and site verification.
