3. Lastly, each field needs to be defined, by first adding field title, then name, field type, and, optionally widget, so that this field can be displayed in BT Listing widget.
The ‘contact_address’ is a field title, ‘Address’ is a name, field type is ‘text’, and widget with a slug ‘contact_details’.
Slug – Used for identifying a metabox field, these must be unique, not only within a category, but also within parent and child caregories.
Name – Used for the label of the field.
Field type – Field type being used.
Group of Widget – Where the field will be shown – if it’s one of the existing groups (Amenities, Media, MediaViceo, FAQ) or a new group (can’t be named as one of the existing groups), if it’s a widget, you need to enter ‘widget_slug’, and then the widget slug that you need to enter in the BT Listing widget, in the field slug.
