我尝试让这个示例(http://jsfiddle.net/jhogervorst/Ge7eK/9/)与从左菜单到右的克隆列表元素一起工作。已经有助手:'克隆',但它不起作用 =\
$('ol.sortable').nestedSortable({
disableNesting: 'no-nest',
forcePlaceholderSize: true,
handle: 'div',
helper: 'clone',
items: 'li',
maxLevels: 3,
opacity: .6,
placeholder: 'placeholder',
revert: 250,
tabSize: 25,
tolerance: 'pointer',
toleranceElement: '> div',
/* The magic tric: */
connectWith: '.sortable'
});
