This widget appears to be just what we need, but when added to our sidebar we get some weird overlapping. This seems like a CSS issue we're not sure how to fix. Currently we see:
If we click 2013 it expands as expected, but the 2012 link does not move down the page, so the 'January' link beneath 2013 overlaps with 2012. 'February then appears below it, etc.
The site is live but we're not leaving the widget up because of this issue. Any insight or help would be greatly appreciated.
