Jquery Ui sortable items option select just first item-CodePudding

In my below code just the first #sort-item is sortable, others not. How can I solve it?

$('#sortable').sortable({
   items:"#sort-item"
});

Html;

<ul id="sortable">
    <li id="sort-item"></li>
    <li id="sort-item"></li>
    <li id="sort-item"></li>
    <li id="sort-item"></li>
    <li id="sort-item"></li>
</ul>

Edit: I try;

$('#sortable').sortable({
   items:"> #sort-item"
});

But steal not working

CodePudding user response：

You cannot assign multiple items the same ID (https://www.w3schools.com/html/html_id.asp)

Use a class to select the items:

<ul id="sortable">
    <li ></li>
    <li ></li>
    <li ></li>
    <li ></li>
    <li ></li>
</ul>

$('#sortable').sortable({
  items:".sort-item"
});

or even better, use the element

$('#sortable').sortable({
  items:"li"
});

First using id in multiple element is an html Sementic Error, Id's are used to be in one and only one html element ,

And here that's what causes the issue, just replace in the html your id by a class name and in your js code replace #sort-item by .sort-item see below working snippet :

$('#sortable').sortable({
  items:".sort-item"
});
