The following sample script is useful to transform a list that contains many action links into a single dropdown select box.

Place these codes in Userview Builder > Settings.

window.addEventListener('load', function () {

    setTimeout(function(){
        $("tbody:visible > tr:visible").each(function(){
            actionLink = $("li.action-link-modal").clone();
        
            if($(this).find("td.row_action a").size() > 0){
                $(this).find("td.row_action a").each(function(){
                    $(actionLink).find("ul").append( "<li>" + $(this).prop("outerHTML") + "</li>");
                });
                $(this).find(".footable-last-column").append( actionLink );
                $(actionLink).removeClass("action-link-modal").show();
                $(this).find("td.row_action").not(".footable-last-column").remove();
                $(this).find(".footable-last-column .row_action_inner").remove();
            }
        });
        
        if($("tbody:visible > tr:visible").size() > 0){
            $("th.row_action").not(".footable-last-column").remove();
        }
        
    }, 1000);
    

}, false);

The script above will affect all datalist in the app. If you want to only apply it to a certain datalist, change lines 4 and 18 accordingly by prepending the datalist ID.

This is how line 4 will look like after appending the datalist ID.

$("#requestListAll > tbody:visible > tr").each(function(){

This is how line 18 will look like after appending the datalist ID.

if($("#requestListAll > tbody:visible > tr:visible").size() > 0){
<li class="action-link action-link-modal dropdown" style="display: none; list-style: none; margin: 15px;">
    <a data-toggle="dropdown" class="btn dropdown-toggle waves-effect btn waves-button waves-float" aria-expanded="false">
	     Action
	     <span class="caret"></span>
    </a>
    <ul class="dropdown-menu">
        
    </ul>
</li>
.action-link.open .dropdown-menu {
    width: max-content;
    left: unset;
    right: 0;
}

.action-link .dropdown-menu {
    width: max-content;
    left: auto;
    right: 0;
}
