Using as shipping address the value entered as billing address In Drupal Commerce 2 how can we allow a customer to select as shipping address the same address entered as billing address?
Yes, you can try to custom jquery event.
1.To create a custom js file in your theme folder (/themes/theme-name/js)
Triger Function Like:
$(&quot;select[name='panes[delivery][select_address]']&quot;).change(function()
{
//your code
//.....
});

Thanks
