Show live MLS listings on any Squarespace page with a showcase grid or a carousel. The cards update on their own.

In short
  • Listing widgets go into the same Embed block.
  • Showcase grid and carousel both work on Squarespace.
  • Filters decide which listings each widget shows.
  • Cards update on their own, nothing to sync.

This guide covers one task from IDX Plugin for Squarespace: putting live listing cards on a Squarespace page. What the cards can do, lead capture, filtering and layout options, is covered in Listing Showcase and Listing Carousel. Here you get the Squarespace-specific part.

This is the showcase grid running live. On your site the same cards show your own MLS listings.

Add the widget to your page

  1. 1 Choose a widget

    In your IDX Plugin dashboard you will find ready demo widgets: Featured Listings List (a grid), Featured Listings Carousel (a single row with arrows) and Most Expensive MLS Listings. You can also create your own targeting specific locations, price ranges or property types.

  2. 2 Configure which listings it displays

    Use the filtering options to control what appears: location, price, property type and more. Adjust the appearance too, including columns, spacing, image ratio and label styles.

About the preview
Squarespace's preview may cut off the widget. On the live site it will display properly as a full listing section.

One widget per page idea

A widget can go on any Squarespace page, not just the homepage. Community pages, a luxury page, a page for one price bracket, each gets its own widget with its own filters, and each updates itself when the MLS changes.

The carousel is the other option, useful when a section should stay short. It is live below.
