Demo

  • You design one page, install a short code snippet, and the plugin handles the rest.

    1. Build your Master Source – Create any standard page on your site and fill it with the content you want to reuse—contact forms, banners, product lists, buttons, or text.

    2. Install and connect – Paste a short code snippet into Squarespace's Code Injection area. Then select your Master Source page and choose which pages should display it as a sidebar.

    3. Update once, sync everywhere – The plugin automatically pulls the Source page's content into sidebars on your chosen targets. Edit the Source page anytime, and every sidebar updates instantly—no copy-pasting required.

    The sidebar uses your site's existing fonts and colors, so it blends in seamlessly. Manage one page, and every sidebar manages itself.

  • The current plugin version is 3.6.1

    Updates:

    • 3.6.1 Fixed the issue caused by the new DOM structure on the 7.1 standalone pages

      After this DOM structure update, the site footer was loading into the sidebar instead of the correct sidebar content.
