To display your sold listings, add one of the display widgets to a page.
The default is to show your active listings.
To show sold properties, edit the embed code to add a filter that specifies the listings to be shown.
In this case, the filter requires two components: first, specify your agent_id, and second, specify listing_status as sold.
For example,Charlie Smith's agent ID is 123456, so the filter would be
filter="agent_id:123456+listing_status:sold"
This should be added to the widget shortcode (Gallery Display for exmple) like this:
Or for WordPress, like this:
[mbb_widget="MBBv3FeaturedGallery" filter="agent_id:123456+listing_status:sold"]
