<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>
Initially, all <li> elements have no hidden attribute and are all visible.
Clicking the button calls JavaScript that toggles the hidden attribute.
