On this page
In short
  • Any search form layout runs on your Squarespace page.
  • The whole form fits once the block is wide enough.
  • Safe Mode shows the finished form before you save.
  • Needs a paid Squarespace plan and a free IDX Plugin account.

The search form on a Squarespace page is one task from IDX Plugin for Squarespace. Any layout from Search Forms, Every Layout Explained works here, and the embed steps follow the same pattern. You need a free IDX Plugin account with your IDX Broker API key added, because that is where the embed code lives. You also need a paid Squarespace plan that allows adding code.

Here is the form itself, running live. This is what lands on your Squarespace page once you paste the code.

Embed the form on your page

  1. 1 Add an Embed block

    Open your Squarespace page editor, click + Add Block, search for "Embed" and add it. The hero section or the area just below it is the usual spot.

  2. 2 Resize the block

    Grab the edge of the embed area and stretch it wide enough to fit the full width of the search form.

  3. 3 Get your embed code

    In a new tab, open your IDX Plugin dashboard. Find the search form widget you want and click Show Embed Code.

Where the search sends visitors

Every search leads to the pages generated from your IDX Broker account: results, single listings, lead forms. Making those pages match your site is its own short task, covered in IDX Property Pages and Your Squarespace Site, with our IDX Broker templates doing most of the work. You can see the search form live on our demo site.
