HTML <ol> hidden Attribute

The hidden attribute on an <ol> tag hides that ordered list. Althought the list is not visible, its position on the page is maintained.

Example

#

A hidden attribute on an <ol> tag.
The ordered list is not visible.

Hidden ordered list:

<p>Hidden ordered list:</p>

<ol hidden>
  <li>Amsterdam</li>
  <li>London</li>
  <li>Berlin</li>
  <li>Paris</li>
</ol>

Using hidden

The hidden attribute hides the <ol> element.

You can specify either 'hidden' (without value) or 'hidden="hidden"'. Both are valid.

A hidden <ol> element is not visible, but it maintains its position on the page.

Removing the hidden attribute makes it re-appear.

  <li>Paris</li>
</ol>

<br />
<button onclick="toggle(this)">Hide ol</button>

<script>
  let toggle = button => {
    let element = document.getElementById("myol");
    let hidden = element.getAttribute("hidden");
    
    if (hidden) {
       element.removeAttribute("hidden");
       button.innerText = "Hide ol";
    } else {
       element.setAttribute("hidden", "hidden");
       button.innerText = "Show ol";
    }
  }
</script>

Code explanation

Initially, this <ol> element has no hidden attribute and is visible.

Clicking the button calls JavaScript that toggles the hidden attribute.

With the hidden attribute the <ol> is not visible.
