I need help figuring out how to eliminate the extra space above 'Smart Filter' in the div id='container_sidebar'. You can view an example of this issue on fiddle http://jsfiddle.net/XHPtc/
It seems that if I remove the float: right property from the 'container_sidebar' div, the extra space above will disappear. However, this would disrupt the layout. Any suggestions on what might be causing this bug?
