Search bar in the Feed template

Hello!

Just 2 questions (i'm using the feed template):

1_ I've added the search function, but using the code in my custom HTML:
<script type="text/javascript">
$(document).ready(function() {
$("#header_content").append($('#search_form'));
});
</script>

from here: http://support.cargocollective.com/discussion/20612/how-to-make-the-search-to-stay-in-navigators/p1

How do I keep the search bar from scrolling when scrolling down the page?


2_ After searching something in the search bar, the search bar jumps to the left a few pixels, how can I stop it from doing that

Thanks!
Dale
