how do i make a select box populate div on change
<p>so, I have read just about every question on this subject, but the solutions don't work for my project, it seems that when I change the dropdown, it does the first event, but when I change to a different element it doesn't do anything else, but when I do this with an alert message it changes every time. </p>

<p>here is what I have to demonstrate what I mean</p>

<p>I tried .post it works great until I add php and all the dynamic functions, is it because I used $('#updateDiv').html(url);</p>

<p>I also hide and showed the div based on the change of the dropdown, but all that did was hid and show the div, I want the div to show the content based on a list of categories.</p>

<p>the PHP side will be dynamic, but if I do .html() none of the php renders properly.</p>
