Hi @simpleways
I believe you can hide the number using CSS like this:
function my_acf_admin_head1() {
?>
<style type="text/css">
.acf-field-56d9c106c8503 .acf-row-handle.order span{visibility: hidden;}
.acf-field-56d9c106c8503 .acf-row-handle.order span:before{visibility: visible;}
</style>
<?php
}
add_action('acf/input/admin_head', 'my_acf_admin_head1');
Hope this helps!
