How to Add a Hide Open Button to Rank Math TOC Block

📜 The Table of Contents (TOC) is an essential feature for long-form content, offering a roadmap to readers and enhancing the user experience. While many WordPress plugins provide TOC functionality, RankMath is a popular choice that not only offers SEO features but also a TOC block.

😕 However, one limitation is that the TOC is always open by default, and there’s no built-in option to toggle it. In this blog post, we’ll guide you through the process of adding a hide/open button to the Rank Math TOC block in WordPress posts. 📝

Why Add a Hide/Open Button in Rank Math TOC?

Adding a hide/open button to your TOC can significantly improve the user experience. It allows readers to toggle the TOC, making it less intrusive while they read your content. This feature is particularly useful for mobile users, where screen size is limited. 📱
