<ol>
  <li hidden>Designers</li>
  <li>Developers</li>
  <li>Managers</li>
</ol>

Using hidden

#

The hidden attribute hides the <li> element.

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

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

Removing the hidden attribute makes it re-appear.

<ol>
  <li id="myli">Designers</li>
  <li>Developers</li>
  <li>Managers</li>
</ol>

<br />
<button onclick="toggle(this)">Hide item</button>

<script>
  let toggle = button => {
    let element = document.getElementById("myli");
    let hidden = element.getAttribute("hidden");
    
    if (hidden) {
       element.removeAttribute("hidden");
       button.innerText = "Hide item";
    } else {
       element.setAttribute("hidden", "hidden");
       button.innerText = "Show item";
    }
  }
</script>

Code explanation

Initially, all <li> elements have no hidden attribute and are all visible.

Clicking the button calls JavaScript that toggles the hidden attribute.

Notice that the list item numbering also changes accordingly after the first <li> is hidden.
