javascript - Kendo UI sortable within a sortable

Question

我正在努力使以下工作正常进行:

    <div id="playlist">
        <div id="playlist-title"><span>My Playlist</span></div>
        <ul id="sortable-basic">
            <div class="sortable-div">
                <li>drag div</li>
                <li class="sortable">Papercut <span>3:04</span></li>
                <li class="sortable">One Step Closer <span>2:35</span></li>
            </div>
            <div class="sortable-div">
                <li>drag div</li>
                <li class="sortable">With You <span>3:23</span></li>
                <li class="sortable">Points of Authority <span>3:20</span></li>
            </div>
            <div class="sortable-div">
                <li>drag div</li>
                <li class="sortable">Crawling <span>3:29</span></li>
                <li class="sortable">Runaway <span>3:03</span></li>
            </div>
            <div class="sortable-div">
                <li>drag div</li>
                <li class="sortable">By Myself <span>3:09</span></li>
                <li class="sortable">In the End <span>3:36</span></li>
            </div>
            <div class="sortable-div">
                <li>drag div</li>
                <li class="sortable">A Place for My Head <span>3:04</span></li>
                <li class="sortable">Forgotten <span>3:14</span></li>
            </div>
            <div class="sortable-div">
                <li>drag div</li>
                <li class="sortable">Cure for the Itch <span>2:37</span></li>
                <li class="sortable">Pushing Me Away <span>3:11</span></li>
            </div>
        </ul>
    </div>
    <script>
            $(document).ready(function() {
                $("#sortable-basic").kendoSortable({
                    hint:function(element) {
                        return element.clone().addClass("hint");
                    },
                    placeholder:function(element) {
                        return element.clone().addClass("placeholder").text("drop here");
                    },
                    cursorOffset: {
                        top: -10,
                        left: -230
                    },
                    items: ".sortable, .sortable-div"
                });
            });
    </script>

所以计划如下:您需要能够将 div 上下拖动到其他 div。这很好用。但您还需要能够将单个项目拖入和拖出 div。这是我无法弄清楚的部分。当我单击一个项目时，它仍然会选择 div。对于我的生活，我似乎无法弄清楚这一点。

请尝试下面的代码。

为了您的更多引用，我修改了给定的链接代码: https://docs.telerik.com/kendo-ui/controls/interactivity/sortable/how-to/nested-sortables

$(document).ready(function() {
    
    function placeholder(element) {
        return $("<li style='color: red;' class='sortable' id='placeholder'>Drop Here!</li>");
    }

    $("#sortable-basic").kendoSortable({
        connectWith: ".sortable-div",
        filter: ".sortable", // Filter only list items that are direct child of the Sortable container.
        // Use ".list-item" to allow parent items to use the nested Sortable.
        
        placeholder: placeholder
    });
    $(".sortable-div").kendoSortable({
        connectWith: "#sortable-basic",
        filter: ".sortable",
        placeholder: placeholder
    });
});

#example {
    -webkit-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
}

#playlist {
    margin: 30px auto;
    width: 300px;
    background-color: #f3f5f7;
    border-radius: 4px;
    border: 1px solid rgba(0,0,0,.1);
}

#playlist-title span {
    display: none;
}

#sortable-basic {
    padding: 0;
    margin: 0;
}

li.sortable {
    list-style-type: none;
    padding: 6px 8px;
    margin: 0;
    color: #666;
    font-size: 1.2em;
    cursor: move;
}

li.sortable:last-child {
    border-bottom: 0;
    border-radius: 0 0 4px 4px;
}

li.sortable span {
    display: block;
    float: right;
    color: #666;
}

li.sortable:hover {
    background-color: #dceffd;
}

li.hint {
    display: block;
    width: 200px;
    background-color: #52aef7;
    color: #fff;
}

li.hint:after {
    content: "";

    top: 8px;
}

li.hint:last-child {
    border-radius: 4px;

li.hint span {

li.placeholder {
