jquery - jQuery sortable and nested lists

Question

I have a large list that I am trying to get so its sortable.

I would like the parent items .cat-title to be sortable between each other and this will move the children along with them. but then I would like the .cat-title's children to be sortable between each .cat-title.

Its like categories and sub items but jQuery sortable just is not doing what I had expected it to do

jQuery

$(function() {
    $( "#user-stream-list > .feed" ).sortable();
});

Answer 1

あなたのセレクターは、すべてのliをソートしようとしているだけです。Sortable は、個々のリスト (具体的には ul タグ) ごとに呼び出す必要があります。これは、物をドラッグできる場所の境界を決定するものです。したがって、各リストに ID を与えてから、それらをすべてソート可能にします。（下を見てください）

<ul id="user-stream-list" class="user-stream-list">
<li class="feed ui-sortable "><span class="cat-title" data-title="5">Apple</span>
    <ul id="appleSub">
        <li class="feed sub"><a data-uid="15" data-fid="11" href="http://appleinsider.com/appleinsider.rss"><img src="https://www.google.com/s2/favicons?domain=appleinsider.com" class="favicon"><span class="title">AppleInsider</span><span class="options"><span data-fid="11" class="addcat">+</span><span class="delete">×</span></span></a></li>
        <li class="feed sub"><a data-uid="15" data-fid="29" href="http://9to5mac.com/feed/"><img src="https://www.google.com/s2/favicons?domain=9to5mac.com" class="favicon"><span class="title">9to5Mac</span><span class="options"><span data-fid="29" class="addcat">+</span><span class="delete">×</span></span></a></li>
    </ul>
</li>
<li class="feed ui-sortable"><span class="cat-title" data-title="15">Gadgets</span>
    <ul id="gadgetSub">
        <li class="feed sub"><a data-uid="15" data-fid="2" href="http://www.engadget.com/rss.xml"><img src="https://www.google.com/s2/favicons?domain=www.engadget.com" class="favicon"><span class="title">Engadget</span><span class="options"><span data-fid="2" class="addcat">+</span><span class="delete">×</span></span></a></li>
        <li class="feed sub"><a data-uid="15" data-fid="59" href="http://feeds.gawker.com/gizmodo/vip"><img src="https://www.google.com/s2/favicons?domain=feeds.gawker.com" class="favicon"><span class="title">Gizmodo</span><span class="options"><span data-fid="59" class="addcat">+</span><span class="delete">×</span></span></a></li>
    </ul>
</li>
<li class="feed ui-sortable"><span class="cat-title" data-title="9">Tech Crunch</span>

jQuery

$(function() {
    $( "#user-stream-list" ).sortable();
});
$(function() {
    $( "#appleSub" ).sortable();
});
$(function() {
    $( "#techSub" ).sortable();
});
$(function() {
    $( "#gadgetSub" ).sortable();
});
$(function() {
    $( "#uncatSub" ).sortable();
});

Answer 2

sortable 関数を から に移動すること<li>に<ul>加えて、stopPropagation を sortable の dragstart イベントに追加する必要がありました。これにより、無限にネストされたリストが適切に機能します。

items.attr('draggable', 'true').on('dragstart.h5s', function(e) {
    e.stopPropagation(); // add this line to jquery.sortable.js
    .....
}

次に、 sortable() が呼び出されたときに、リストをすべて「接続」する必要があります。

$('.sortable').sortable({ connectWith: '.sortable' });

私の経験では、タグに移動する<ul>だけでは、子がクリックされても最上位のリスト項目しか移動しませんでした。
