React-Bootstrap add pull-right to Button : <p>I have the following JSX using React-Bootstrap:</p>

<pre><code>&lt;Button bsStyle="danger pull-right" bsSize="small" onClick={() =&gt; {alert('do stuff')}}&gt;
    &lt;Glyphicon glyph="trash" /&gt;
&lt;/Button&gt;
</code></pre>

<p>However this will show a warning in the console:</p>

<pre><code>Warning: Failed prop type: Invalid prop `bsStyle` of value `danger pull-right` supplied to `Button`, expected one of ["success","warning","danger","info","default","primary","link"].
</code></pre>

<p>What is the best way to add <code>pull-right</code> to the list of styles?</p>

<p>The above code does work, but I'd prefer not to have any warnings in my console.</p>
