Knockout nested sortable lists
问题 I need to build a web page that has two lists that can be swapped around. The lists have items that can also be swapped or moved from one list to the other. I used knockoutjs and knockoutjs-sortable to implement this. HTML <ul class="Tasks" data-bind="sortable: TaskLists"> <li class="taskList"> <span data-bind="text: Title" style='background: lightgray;'></span> <ul data-bind="sortable: Tasks"> <li class="item"> <span class="taskName" href="#" data-bind="text: name"></span> </li> </ul> </li>
