title: Is it possible to prevent default onDeselect, (select input multiple ant design)?
body: <p>What I´m trying to do is to control the onDeselect event, I want to ask a question before the event finish. And then if the user accept delete the option could be deleted.</p>
  
  <p>This is my select and the props:</p>
  
  <pre><code>&lt;Select
         mode="multiple"
         style={{ width: '100%' }}
         placeholder="Select at least one"
         allowClear={false}
         onSelect={this.addNewClassroom}
         onDeselect={this.deleteClasroom}
        &gt;
          {classroomSelect}
  &lt;/Select&gt;
  </code></pre>
  
  <p>This is the function that I use:</p>
  
  <pre><code>deleteClasroom(val, e){
  
      //e.preventDefault();
  
      confirm({
        title: 'Are you sure?',
        content: 'Delete this...',
        onOk() {
          //  -----------&gt; delete the item 
        },
        onCancel() {
          //  -----------&gt; keep the item 
         },
      });
    }
  </code></pre>
