Title: Fixes #228 and #242

This commit fixes #228 again, as it was only fixed in Google Chrome 20 and reappeared in Internet Explorer 9.
This removed the conditional positioning of the drop-down in `postRender` as it needed to be re-positioned every time.

This commit also fixes #242 (it was never fixed with the most recent commit) to allow widths to be set via CSS and adds support for percentages automatically. This was done by replacing the search through the element styles which is not consistent.
