Squarespace Slide-out

Squarespace 7.1 lets you add a second footer section that most sites never use. Squarespace Slide-out from SQS Mods turns that spare section into a panel that slides in over the page when a visitor clicks a trigger: a contact form, your latest blog posts, an Instagram feed, an FAQ accordion, or anything else you can build in a Squarespace section. Because it is a real section, the native settings for colours, fonts and background still apply, and any linkable element (a button, image block, text link, header button or navigation link) can be the trigger. Options cover panel width for desktop and mobile, slide speed, which edge it enters from, the close label and colour, background blur and opacity, and whether the page behind stays scrollable. It is a code plugin for Squarespace 7.1 only, not the interface-component plugin an earlier version of this page described.

Who it suits

Service businesses that want a contact form reachable from every page, shops with a quick view of new posts or products, and designers who like off-canvas panels but do not want to hand-code one.

One honest caveat

The plugin uses your secondary footer section, so that section is no longer available for anything else, and there is one slide-out per site. Navigation folders cannot be used as triggers. It is 7.1 only, needs a Business plan or higher, and SQS Mods do not offer refunds on digital products.

Installation

Add the code following SQS Mods' instructions, build the panel content in the secondary footer section and assign the trigger to your chosen link. SQS Mods say it takes about five minutes.

SQS Mods build their plugins from problems that came up on real client sites, a story we cover in why every SQSMODS plugin starts with a real client problem.
