Multiple Categories in DB
<p>I want to create a page where you can select a category link and then it will show the categories under that category kinda like steps going downward. I want to do my db table like this </p>

<pre><code>table [categories]
pk categoryID
categoryName
parentID
level 
</code></pre>

<p>that parentID links itself back to the categoryID. Is there any tutorials out there that shows this demonstration I haven't found any. Or is there a better way todo this.</p>
