<p><img src="http://i.stack.imgur.com/pZeop.jpg" alt="enter image description here"></p>

<p>I want put a scrollbar into the dropdownlist opened (picklist) because this is overflowing the height of this page.</p>

<p>This is my code:</p>

<pre><code> var picklist = function (msg) {

    var $selectall = $(this).find('[data-dropdown-selectall]');
    var $filter = $(this).find('[data-dropdown-filter]');
    var $inner = $(this).find('.picklist-inner');
    var propertyName = $(this).attr('data-dropdown-property');
    var friendlyName = $(this).attr('data-dropdown-friendlyname');
    var $name = $(this).find('.picklist-header span');

    $inner.maxHeight = 12;

    $selectall.bind('click', function(e) {

        var checked = $selectall.is(':checked');

        $inner.children().each(function (i, v) {
            var chk = $(this).find('input');

            if (i &gt; 0) {
                if (checked) {
                    chk.attr('checked', checked);                        
                } else {
                    chk.removeAttr('checked');
                }
             }
         });
    });
</code></pre>

<p>Someone has some tip?</p>

<p>Thank in advance</p>
