Isotope regex search filtering by word at the beginning of line
<p>I would like to filter results in Isotope by matching only beginning of line strings. I know regexp should be something along the lines of [/^\b($string)/igm] <a href="http://regexr.com/3e9gc" rel="nofollow">http://regexr.com/3e9gc</a> but I can't seem to make it work.</p>

<p>Here is Isotope's own codepen example on which I have tried to apply this regexp:
<a href="http://codepen.io/anon/pen/pENYZE" rel="nofollow">http://codepen.io/anon/pen/pENYZE</a></p>

<pre><code>qsRegex = new RegExp( "\\b("+$quicksearch.val()+")", 'gmi' );
</code></pre>

<p>... is the code line in question. I can't seem to properly include ^ as well.</p>

<p>In Search field start typing <strong>Ca</strong> - Calcium, Cadmium and edited Rhenium Cadmiumca will appear. <i>Third one shouldn't be there (or any other combination)</i>.</p>

<p>Thank you for your help.</p>
