SimpleTOC – Table of Contents Block vs OffCanvas / Drawer – Responsive Slide-In Drawer & Popup System

OffCanvas / Drawer is a flexible, highly customizable, and lightweight WordPress Gutenberg block that lets you design slide-in drawers, off-canvas navigation menus, and popup panels that slide in from any direction: left, right, top, or bottom. Perfect for mobile navigation menus, WooCommerce shopping cart sidebars, newsletters, exit-intent popups, slide-out contact forms, site announcements, and help desks — all without writing a single line of code. Built natively for the WordPress Block Editor, it supports InnerBlocks, meaning you can place any other Gutenberg blocks (paragraphs, images, forms, custom widgets) directly inside the OffCanvas drawer. It also features a custom shortcode generator allowing you to save layouts and embed them anywhere on your site using the [offcanvas-block id="POST_ID"] shortcode. The plugin is fully responsive, SEO-friendly, performance-optimized, and built to integrate seamlessly with any WordPress theme.

Add a Table of Contents block to your posts and pages. The TOC is a nested list of links to all heading found in the post or page. To use it, simply add a block and search for “SimpleTOC” or just “TOC”. The maximum depth of the toc can be configured in in the blocks’ sidebar among many other options. There can hide the headline “Table of Contents” and add your own by using a normal heading block. Spin up a new WordPress instance with the SimpleTOC plugin already installed.
