List Grid Pop-up

What You'll Create

Build an interactive grid layout in Squarespace where list items display as bordered cards with hover previews, and clicking reveals a detailed side-panel overlay with full content. The popup slides in smoothly from the right while the grid maintains its visual structure with customizable border gaps.

The Problem It Solves

Standard list sections force visitors to leave the page to view detailed content, breaking the browsing flow. This technique keeps users engaged by revealing additional information in an overlay panel while maintaining context of the grid layout. Perfect for presenting multiple items that need both overview and detail views.

Perfect For

Service providers showing package details, agencies displaying project case studies, consultants presenting methodology steps, restaurants featuring menu items, real estate showcasing property details.

What Makes This Different

This technique uses consistent 3-pixel border spacing throughout the grid for a clean, uniform look. Creates a bordered grid effect using creative border placement on items and containers. Implements a 40% width side panel that becomes full-width on mobile. The popup content follows your scroll as you read through details. Includes smooth 0.3-second transitions for opening and closing. Handles scroll locking when popup is active on mobile so the background stays fixed.
