Overview
Squarespace has no reusable block: if the same newsletter form, promotion banner, disclaimer or contact details appear on twenty pages, you edit them twenty times. Synced Blocks For Squarespace from BeyondSpace adds that missing feature. You create a blog collection called Reusables, save each piece of content as a post, and place it anywhere on the site with a Summary Block filtered by that post's tag. Edit the post once and every instance updates. It works with text, images, video, forms, newsletter blocks, buttons, galleries and code, the content is rendered on the page rather than loaded dynamically so search engines index it, and you can schedule a block to appear or disappear using the post's publish settings. BeyondSpace state it works on 7.1 and 7.0 templates, including Brine and Tremont.
Who it suits
Designers managing large sites, businesses with site-wide notices or promotions, and anyone who has outgrown Squarespace's Saved Sections, which do not update automatically and are capped at fifty per site.
One honest caveat
The workflow is unusual. Your reusable content lives in blog posts and is placed with Summary Blocks, so you are working within Summary Block layouts rather than dropping a block straight into a page, and it takes a short tutorial to get comfortable. A change to a synced block changes it everywhere, which is the feature, but there is no per-page override. It needs a Core plan or higher (Business or Commerce on older plans).
Installation
Add the plugin code following BeyondSpace's instructions, create the Reusables blog with the URL slug /reusables, then build your first synced post and use the Sync Content button to save it. Add ?reveal-reusables to a page URL to highlight every synced block on it.
