Bootstrap navbar style change on toggle
<p>I am using a WP theme(bootstrap). When resize my window to mobile view, i see a button of toggle menu (3 horizontal lines). On clicking it, i see a drop down type list of pages. </p>

<p>I want to change that drop down to open like right to left. 
Just like this : <a href="http://html5up.net/spectral" rel="nofollow">Here is the link</a> </p>
