Hello,

Could you please provide more details on your scenario and describe step-by-step the user actions that lead to the issue you have experienced?

I am attaching a sample project with the IE8 compatibility set in the web.config. At my side the PanelBarItems expand correctly in both IE8 and IE11. Please try to reproduce the problematic behavior in it and post your modifications so we can further investigate the issue.
