Sortablejs 拖放多个容器

Question

sortablejs is a drag and drop plugin link

How the plugin working

<div id="example3Left"> 
<div class="list-group-item"> Item 1</div>
<div class="list-group-item"> Item 2</div>
<div class="list-group-item"> Item 2</div>
</div>
<div id="example3Right">
// Element dropping block
</div>
 

    new Sortable(example3Left, {
        group: {
            name: 'shared',
            pull: 'clone' // To clone: set pull to 'clone'
        },
        animation: 150
    });
    
    new Sortable(example3Right, {
        group: {
            name: 'shared',
            pull: 'clone'
        },
        animation: 150
    });

Check below code - But I have multiple "example3Left" container so how can I use with class name instead of ID example code but not working

<div class="group group-1"> 
<div class="list-group-item"> Item 1</div>
<div class="list-group-item"> Item 2</div>
<div class="list-group-item"> Item 2</div>
</div>
<div class="group group-2"> 
<div class="list-group-item"> Item 1</div>
<div class="list-group-item"> Item 2</div>
<div class="list-group-item"> Item 2</div>
</div>
<div id="example3Right">
// Element dropping block
</div>
new Sortable($('.group).get( 0 ), {
        group: {
            name: 'shared',
            pull: 'clone' // To clone: set pull to 'clone'
        },
        animation: 150
    });

    new Sortable(example3Right, {
        group: {
            name: 'shared',
            pull: 'clone'
        },
        animation: 150
    });

Answer 1

you have to loop

 $('.group, #example3Right').each((i, el) => { new Sortable(el, { group: { name: 'shared', pull: 'clone' // To clone: set pull to 'clone' }, animation: 150 }); })

 .list-group-item{border: 1px solid #bbb;width:100px;margin:5px}
