<script type="text/javascript">
         $(document).ready(function() {
              $('.dragger').mousedown(function (event) {
                  $(this)
                      .data('down', true)
                      .data('x', event.clientX)
                      .data('scrollLeft', this.scrollLeft)
                      .addClass("dragging");

                  return false;
              }).mouseup(function (event) {
                  $(this)
                     .data('down', false)
                     .removeClass("dragging");
              }).mousemove(function (event) {
                  if ($(this).data('down') == true) {
                      this.scrollLeft = $(this).data('scrollLeft') + $(this).data('x') - event.clientX;
                  }
              }).mousewheel(function (event, delta) {
                  this.scrollLeft -= (delta * 30);
              }).css({
                  'overflow' : 'hidden',
                  'cursor' : '-moz-grab'
              });
              $(window).mouseout(function (event) {
              if ($('.team-form-data').data('down')) {
                  try {
                      if (event.originalTarget.nodeName == 'BODY' || event.originalTarget.nodeName == 'HTML') {
                          $('.team-form-data').data('down', false);
                      }
                  } catch (e) {}
              }
         });
             });
      </script>

Thank you. Am I free to use it in one of my web designs or are there any restrictions on it?
