How Do I Add a Table of Contents to Long Webflow Blog Posts in 2026?

Why does a long blog post need a table of contents?

A table of contents gives readers a map of a long post and lets them jump straight to the section they want. On a 2,000-word article, most people do not read top to bottom. They scan for the part that answers their question. A short list of links at the top respects that habit, keeps people on the page longer, and can help search engines understand how your article is organized.

There is a second benefit that matters more every year. AI answer engines and search crawlers read structure, not just words. When your headings are clear and linked, a machine can see the shape of your article at a glance. A table of contents built from real heading links is a simple way to make that structure obvious to both a reader and a crawler.

What is a table of contents made of, technically?

A table of contents is just a set of links that point to headings on the same page. Each heading gets an ID, which is a unique name in the HTML. Each link in the list uses that ID as its target, written with a hash in front. When someone clicks the link, the browser scrolls to the heading with the matching ID. That is the whole mechanism.

Because it relies on IDs, the work splits into two small jobs. First, give every section heading a clear, unique ID. Second, build a list of links that point to those IDs. Once you understand that a table of contents is only links and IDs, it stops feeling like a special feature and starts feeling like something you can build by hand in Webflow.

How do I add IDs to my headings in Webflow?

In Webflow, you add an ID to an element through the settings panel, in the field for the element ID. For a static heading on the canvas, you select the heading, open the settings tab, and type a short, lowercase ID with no spaces. For headings inside a Rich Text element, which is where most blog bodies live, the approach is a little different and needs a small extra step.

Rich Text elements do not expose an ID field for each heading in the same way. The common fix is to use the Rich Text element's support for heading anchors, or to add the IDs with a short embed of custom code that assigns them when the page loads. I keep the IDs short and readable, like why-it-matters, so the final links stay clean and easy to check.

How do I build the actual list of links?

You build the list as a set of text links, each pointing to one heading ID. In Webflow, you add a link element for each section, set its text to the section name, and set its link target to the ID with a hash in front, like hash why-it-matters. Stack those links in a container at the top of the post, and you have a working table of contents.

I keep the list in a plain style rather than a heavy boxed widget, so it feels like part of the article. Each link reads like a real question or section title, which also tells the reader what the post covers before they commit to reading. This pairs well with the jump-link technique I explained in how to add smooth-scroll anchor links to a Webflow one-page site, since the underlying idea is the same.

How do I make the scroll smooth instead of jumpy?

By default, clicking an anchor link makes the page jump instantly to the heading, which can feel abrupt. You can soften that with a single line of CSS, scroll-behavior set to smooth, applied to the page. With that in place, the browser glides to the target instead of snapping to it. No JavaScript is needed for the basic effect in modern browsers.

One thing to watch is a sticky header. If your site has a fixed nav bar at the top, a smooth scroll can land with the heading hidden behind it. The fix is to add a small amount of scroll padding so the target stops just below the header. I test this on a real phone, since sticky headers behave differently on small screens, and a heading tucked under the nav is easy to miss on desktop.

Should the table of contents follow the reader down the page?

A sticky table of contents that stays visible as the reader scrolls is a nice touch on very long posts, but it is optional. On a wide screen, you can place the list in a column to the side and make it sticky, so the reader always sees where they are. On a phone, screen space is tight, so I usually keep the list at the top and let it scroll away.

I only add the sticky version when a post is genuinely long, past fifteen hundred words or so, where a reader might want to jump around more than once. For a shorter piece, a simple list at the top is enough and adds less clutter. This is a good companion to a scroll progress indicator on Webflow blog templates, which shows how far along the reader is without taking up much room.

Does a table of contents help with accessibility?

Yes, when it is built with real links, a table of contents helps people who navigate with a keyboard or a screen reader. These readers often move through a page by jumping between links and headings. A clear list of in-page links gives them a fast way to reach the section they need, the same way it helps a sighted reader who is scanning with their eyes.

For this to work, the links need readable text, not just an arrow or a number. A screen reader announces the link text, so section three is far less useful than how do I add IDs to my headings. Clear heading text does double duty here. It labels the section for everyone and makes the table of contents meaningful for the people who rely on it most.

What is the simplest version I can ship today?

The simplest version is a short list of text links at the top of the post, each pointing to a heading ID, with smooth scroll turned on. That is it. You do not need a plugin, a widget, or a script for a basic, working table of contents. Add the IDs, build the links, turn on smooth scroll, and test each link once.

Once that works, you can decide whether a longer post deserves the sticky, side-column treatment. Start simple and grow it only where the length calls for it. If you want a reusable table of contents component you can drop into every Webflow blog post, or help wiring the IDs into your Rich Text template, I am happy to walk through it. Let's connect.
