<h2>Description</h2>
<div class="description">
  <p>Binding to the <code>multiple</code> attribute of <code>select</code> element is not supported since switching between multiple and single mode changes the <a href="api/ng/directive/ngModel"><code>ngModel</code></a> object type from instance to array of instances which breaks the model semantics.</p>
<p>If you need to use different types of <code>select</code> elements in your template based on some variable, please use <a href="api/ng/directive/ngIf">ngIf</a> or <a href="api/ng/directive/ngSwitch">ngSwitch</a> directives to select one of them to be used at runtime.</p>
<p>Example with invalid usage:</p>
<pre><code>&lt;select ng-model=&quot;some.model&quot; multiple=&quot;{{mode}}&quot;&gt;&lt;/select&gt;
</code></pre>
<p>Example that uses ngIf to pick one of the <code>select</code> elements based on a variable:</p>
<pre><code>&lt;select ng-if=&quot;mode == &#39;multiple&#39;&quot; ng-model=&quot;some.model&quot; multiple&gt;&lt;/select&gt;
&lt;select ng-if=&quot;mode != &#39;multiple&#39;&quot; ng-model=&quot;some.model&quot;&gt;&lt;/select&gt;
</code></pre>
