Full Bootstrap 3 compatibility in v0.9.3
Bootstrap 3's global usage of box-sizing: border-box
was causing incorrect sub menus positioning in some browsers like Chrome so we've addressed this in v0.9.3 which is now available. SmartMenus jQuery should now be considered fully compatible with Bootstrap 3.
Note: The actual fix is in the "sm-core-css.css" file so make sure you update it too if you are upgrading.
