<p>I have 2 tables, Categories and Sub Categories. Is it prossible to present all sub categories in a checkbox list arraged by their cagetories? </p>

<p>Something like this:</p>

<p>Category 1</p>

<ul>
<li>sub category checkbox1</li>
<li>sub category checkbox2</li>
</ul>

<p>Category 2</p>

<ul>
<li>sub category checkbox3</li>
<li>sub category checkbox4</li>
</ul>

<p>Category 3</p>

<ul>
<li>sub category checbox5</li>
</ul>
