In this tutorial, we'll demonstrate how to collapse the Table of Contents (TOC) in the Rank Math SEO plugin using a combination of JavaScript and CSS. This will enhance the user experience by allowing visitors to toggle the visibility of the TOC content.
Steps to Collapse the Table of Contents in Rank Math
The Rank Math TOC block is displayed by default, but you can make it collapsible with a few simple steps. Follow these instructions to achieve a collapsible TOC block.
Step 1: Add JavaScript Code
To make the TOC block collapsible, add the following JavaScript code to your site. You can do this by using a Code Snippet plugin or by adding it directly to your theme’s functions.php file.
function turn_rm_toc_collapsable() {
?>
<script>
document.addEventListener("DOMContentLoaded", function() {
var tocItems = document.querySelectorAll("div.wp-block-rank-math-toc-block");
tocItems.forEach(function(tocItem) {
tocItem.addEventListener("click", function(event) {
var nav = tocItem.querySelector("nav");
if (nav.style.overflow === "hidden" || nav.style.overflow === "") {
nav.style.overflow = "visible";
nav.style.maxHeight = "100vh";
} else {
nav.style.overflow = "hidden";
nav.style.maxHeight = "0";
}
});
});
});
</script>
<?php
}
add_action('wp_footer', 'turn_rm_toc_collapsable');
This JavaScript code enables the TOC block to toggle between expanded and collapsed states by adjusting the overflow and maxHeight properties of the nav element within the TOC block.
Step 2: Style the TOC Block
Next, enhance the appearance of the TOC block with CSS. Add the following CSS code to your theme’s style.css file or use a custom CSS plugin:
.wp-block-rank-math-toc-block {
position: relative;
}
.wp-block-rank-math-toc-block h2 {
background: #f1f2f6;
padding: 10px 12px 10px 18px;
cursor: pointer;
font-size: 18px !important;
font-weight: normal !important;
position: relative;
margin-bottom: 0;
}
.wp-block-rank-math-toc-block h2:before {
display: inline-block;
content: "";
width: 0;
height: 0;
border-style: solid;
border-width: 6px 0 6px 12px;
border-color: transparent transparent transparent #000000;
margin-right: 8px;
}
.wp-block-rank-math-toc-block nav {
padding: 10px 10px 0px 10px;
max-height: 0;
overflow: hidden;
transition: max-height 0.3s ease, overflow 0.3s ease;
}
This CSS code styles the TOC block, including the heading to make it clickable, adjusts padding, and adds a transition effect for a smooth animation when toggling the visibility of the TOC content.
