I would like to confirm that we tested the a scenario with RadMenu version 2013_2_717 and Bootstrap 2.0.1 but we were not able to replicate the described problem. Could you please confirm that the problem you are facing is that the second column of items for some reason goes on the next line right below the first one. So eventually it looks like the RadMenu items are rendered in a single column instead of two?
Please note that we have tested the both render mode - the classic and the lightweight. We are sending you this video
for your reference. We are sending you the tested project in the attachment. Please let me know if there is something different in your scenario that I am missing.
Thank you for your understanding.
