I'm trying to get the value selected by the user in my dropdown form to be send with my email.

The values are generated with this code :

function wpb_hook_javascript() {
?>
<script type="text/javascript">
    var myDiv = document.getElementById("myDiv");
    var selectList = document.createElement("select");
    selectList.id = "mySelect";
    myDiv.appendChild(selectList);
    var activite = document.querySelectorAll(".info-box-content h3");
    console.log (activite);
    for (var i = 0; i < activite.length; i++) {
        var array = activite[i].innerText;
        console.log (array);
        var option = document.createElement("option");
        option.value = array;
        option.text = array;
        selectList.appendChild(option);
    }
    console.log ("retour var array : " + array);


</script>
<?php
}
add_action('wpforms_wp_footer', 'wpb_hook_javascript');

With it I get the different values on my page in the class info-box-content as h3 and make them options values for my dropdown inserted in the myDiv DIV in my form.

With the code below I want to add the HTML block with the myDiv DIV in my notification email :

function wpf_dev_email_display_other_fields( $fields ) {
    return array( 'divider', 'pagebreak', 'html' );
}
     
add_filter( 'wpforms_email_display_other_fields', 'wpf_dev_email_display_other_fields', 10, 1 );

Everything works fine except that the value selected by the user is not in the email content.
