jQuery可排序佔位符水平divs

Question

我想讓佔位符jQuery排序。我得到這個代碼

$('#list').sortable({ 
    placeholder: "testclass", 
    forcePlaceholderSize: true 
}); 
<div id="list"> 
    <div class="item">First</div> 
    <div class="item">Second</div> 
    <div class="item">Third</div> 
</div> 
.item { 
    border: 1px solid black; 
    padding: 2px 4px; 
    display: inline-block; 
} 
.testclass { 
    background-color: red; 
    border: 2px solid red; 
}

但它不似乎運作良好

Answer 1

嘗試使佔位符inline-block的

.testclass { 
    background-color: red; 
    border: 2px solid red; 
    width: inherited; 
    display: inline-block; 
}
