title: Reactjs with LinkedStateMixin and select with multiple options
body: <p>Using Reactjs, I want to have a single handleChange method handling the modifications of all my form elements.</p>
  
  <p>I understand that the <a href="http://facebook.github.io/react/docs/two-way-binding-helpers.html" rel="nofollow">LinkedStateMixin</a> exists for this reason, and that I should use </p>
  
  <pre><code>render: function() {
      return &lt;select multiple={{ true }} valueLink={this.linkState('value')}&gt;...options...&lt;/select&gt;;
    }
  </code></pre>
  
  <p>to bind the status of my select element.</p>
  
  <p>But it seems that this way of doing things does not work with multiple selects : the state.value is updated but with only one value (when I select 2 options, I can see React update the DOM and it systematically removes one of the selection).</p>
  
  <p>So my question is : is LinkedStateMixin a dead-end for this use case ? How do you handle this select-multiple use case ?</p>
