Quick Tip: Add a Table of Contents to the Beginning of Your Blog Posts

When I write longer articles here on Kolakube, I like to add a Table of Contents to the top to help my reader’s navigate to different sections of the post.

Lately a lot of you have been asking how I did it, so this post is my quick explanation showing how (of course, I’ll be referencing to Marketers Delight as that’s the theme I use here).

Step 1: Install Table of Contents Plus

I usually like to build features like this myself, but when I found Table of Contents Plus I knew it would just be a waste of time because this plugin nails it.

It’s a free plugin from the WordPress repository, so search for “Table of Contents Plus” from the Plugins screen in your Dashboard to find it.

Once you install it, go ahead and activate it.

Step 2: Configure Some Settings

This plugin comes with a very detailed options panel. These options do more than I need, but the author made it very easy to turn different settings on/off.

Here’s a screenshot of the settings I configured below. You may make tweaks based on your own preferences and the theme you’re using on your site.

Again, I made these decisions based on my own preferences and the fact that Marketers Delight takes care of most of the styling.

Also, I prefer to manually insert the Table of Contents into my posts rather than the plugin adding it to every post/page. I’ll show you that in the next step.

3. Step 3: Add the Shortcode to Your Posts

Table of Contents shortcodeThe final step to adding a table of contents to your posts is to insert the shortcode the plugin provides.

I like to put it at the very beginning, so before any text in the post editor I place the toc shortcode. Nothing to it.

Step 4: Styling Table of Contents in MD

Add this CSS to your Child Theme’s style.css file to add a background color and some spacing:

[class*="toc_wrap"] {
  background-color: #eee;
  font-size: 14px;
  line-height: 22px;
  padding: 26px;
  width: 338px;

You may also position it to the edge of your content box by wrapping the shortcode in your post editor with this little bit of HTML:

<div class="alignright wrap">[toc]</div>

Bonus: Optimize the Scripts + Styles this Plugin Loads

As a developer, I know too much. I know that the scripts and styles this plugin loads on every page of your site won’t be necessary when you don’t have a table of contents on the page. Extra HTTP requests can slow your page down, so I remove them when I can.

I came up with a little function that will load the resources needed for this plugin *only* when you have the [toc] shortcode in your post editor. If not, nothing will load.

Go ahead and paste this function into your Child Theme’s functions.php file (see this for guidance):

Let me know if you have any issues with this, I’ll do my best to help you out.

6 comments add yours

  1. Thanks for the info, Alex. I’m always looking for something that can add to my blog. Here’s one for you: add a plugin that allows commenters to subscribe to comments. It’ll give your visitors a reason to pop back in.

      • That plugin hasn’t been updated in over 2 years. Won’t that cause any problems? Otherwise, great tip Chris!

        • Not necessarily. The guy who made it also builds features into WordPress itself so I trust it.

          Plus it’s pretty popular so I can’t imagine there being anything wrong with such a simple plugin over time (the reviews say it too).

          EDIT: funny, the plugin just got an update.

  2. I was looking for a TOC in a specific book but came across your post and had to take the time to thank you for putting the essential information in the first few ‘graphs and succinctly providing your opinion of the tool. As a wordpress blogger and educator, William Zinsser’s virtues of brevity, clarity, simplicity and humanity are deeply appreciated when and wherever found.
