Slide-Out Panel for Summary Block Items

What You'll Create

A slide-out panel that displays full blog post content when clicking on Summary Block items. Instead of navigating to a new page, the blog post slides in from the right side as an overlay panel, creating an app-like reading experience while keeping visitors on the current page.

The Problem It Solves

Summary Blocks link to full blog posts on separate pages, breaking the browsing flow. When you want visitors to preview or read full content without leaving the current page—like a sidebar reader or quick-view panel—this technique fetches and displays post content in a sliding overlay.

Perfect For

• Blog index pages with quick-read functionality

• News feeds with inline reading

• Portfolio grids with detail panels

• Resource libraries with preview panels

• Any content wanting inline expansion rather than page navigation

What Makes This Different

The JavaScript intercepts Summary Block clicks, fetches the target post content via AJAX, and injects it into a fixed-position slide-out panel. CSS handles the smooth sliding animation and overlay backdrop. The panel includes a close button and clicking outside dismisses it—creating a polished, app-like interaction.
