Hide items within 1 dropdown list using radio buttons jquery
<p>Basically what I want to do is have 1 dropdown list (with all options) and when I click a radio button it only displays specific options from the dropdown list.</p>

<p>For example, I have 2 radio buttons and 6 options:</p>

<pre>
radio-button1, radio-button2

option1,
option2,
option3,
option4,
option5,
option6,
</pre>

<p>If I press <code>radio-button1</code>, it will only display option1, option2, option3 in the dropdown list. If I press <code>radio-button2</code>, it'll display the other 3.</p>

<p>Currently I just use the show/hide functions and 2 separate dropdown list to do this.. but I was wondering how to do it within 1 dropdown list. Any advice would be appreciated cheers.</p>
