October 19, 2021

To reset a dropdown in JavaScript, set selectedIndex to 0.

So if this is your dropdown:

<select id="dropdown">
  <option value="1">One</option>
  <option value="2">Two</option>
  <option value="3">Three</option>
</select>

Then you can reset it like this:

document.getElementById("dropdown").selectedIndex = 0;
