javascript - Animate CSS on selection of <option> -


i attempting trigger change of css objects further down in code when 1 of option tags selected. did not include them here not pertinent issue @ hand jquery. @ loss @ point. here have far...is possible?

<script> $(document).ready(function(){     $("#feed-filter option:selected").change(function () {         $("#ca, #ga, #gd").animate({height: '0px'});     }) }) </script>  <div class="feed-filter">     <select id="feed-filter" name="feed-filter">         <option id="option-all" value="all" selected>all</option>         <option id="option-ca" value="a">a</option>         <option id="option-dad" value="b">b</option>         <option id="option-ga" value="c">c</option>         <option id="option-gd" value="d">d</option>     </select> </div>

firstly aren't triggering css animation, jquery animation. secondly, id's animating don't exist in html, , thirdly, selector/listener invalid, need listen $('select').change();

if need access value of selected option can doing this

$('select').change(function() {     var val = $(this).val(); });
