A “second” dropwdown called “456” must have the value selected on the first called “123” ..
PHP
function my_acf_input_admin_footer() {
?>
<script type="text/javascript">
(function($) {
var x = document.getElementById("acf-field_123"); //first dropdown field
if (x.addEventListener) { // For all major browsers, except IE 8 and earlier
x.addEventListener("change", myFunction);
} else if (x.attachEvent) { // For IE 8 and earlier versions
x.attachEvent("onchange", myFunction);
}
function myFunction(){
var x = document.getElementById("acf-field_123");
var y = document.getElementById("acf-field_456"); //second dropdown
x.value=y.value;
}
})(jQuery);
</script>
<?php
}
add_action('acf/input/admin_footer', 'my_acf_input_admin_footer');
