Can I customise table of contents.

Hello,

Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.

I’m sorry to inform you that, by default, there is no option available to make Rank Math ToC collapsable but if you want you can use the following customize CSS on your site to achieve this:

.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;
}
.wp-block-rank-math-toc-block input:checked+h2~nav {
	max-height: 100vh;
	overflow:visible;
}

Here’s a guide you can follow to add this custom CSS on your site:

Once done, please add this filter to your site: https://pastebin.com/i82VnJ3Z

Here’s how you can add filter/hook to your WordPress site:

Regarding the customization, you can use the default settings to change the color, background color, etc.

But if you want further customization then you’ll have to use custom CSS on your site.

Hope that helps and please don’t hesitate to let us know if you have any other questions.
 
Thank you.

Hello,

It seems to be working fine on our end. If it is not working on your end, we might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.

Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

We really look forward to helping you.
