I use this jQuery to create unordered list elements, nested for subfolders

function show_dirs( ele, folders, prefix ) {
    jQuery.each( folders, function( key, value ) {
        prefix = ( prefix ? prefix + '/' + key : key )
        ele.append( '<li data-key="' + key + '" class="folder" data-prefix="' + prefix + '">' + key + '</li>' )
        if( Object.values( value ).length ) {
            var id = getRandomInt( 100, 999 )
            ele.find( 'li[data-key="' + key + '"]' ).append( '<ul id="folder_' + id + '" class="folders"></ul>' )
            show_dirs( ele.find( '#folder_' + id ), value, prefix )
        }
        prefix = ''
    })
}
