Get Started
Be aware that this only serves as a temporary solution.
Step 1
Drag a custom HTML into the designated form
Step 2
Paste the following code. This will add a download all button to the form to perform bulk download files.
<div id="download-all" class="btn btn-primary">Download All</div>
<script>
$(function(){
searchParams = new URLSearchParams(window.location.search) // to check the mode
mode = searchParams.get("_mode");
if(mode == 'add'){// hide if its "add" mode
$('#download-all').hide();
}
$('#download-all').on('click', function(){
links = $("ul.form-fileupload-value").find("a:not(.remove)"); // get all <a> tag except those with "remove" class
$.each(links, function(k,v){ // iterate through them 1 by 1, while using click() on them.
v.click();
})
})
});
</script>
