Some components need a bit of custom JavaScript to work properly. Elementor gives you a couple of easy ways to add it.
Go to WordPress Dashboard → Elementor → Custom Code. Click Add New, then paste your JavaScript. Make sure it’s wrapped in a script tag like this:
<script>
// your JS here
</script>
Choose where it should load (usually Body End), then publish it.
You can also control where the script runs, such as:
Edit the page in Elementor, add an HTML widget, and paste your script there, also wrapped in <script>...</script>.
