Alter dropdown options dynamically
<p>I want to create 2 select boxes. The option of the first box chosen will decide the options visible in the second select box. For example: </p>

<p>Select box A contains options 2010, 2011, 2012</p>

<p>Select box B contains movies names according their release year.</p>

<p>Now when say option 2012 is selected in box A, only those movies which have their release year on 2012 are displayed.</p>
