Hi. Am using Dreamweaver CS6 and my Spry Horizontal Menu Bar is playing up.
It's insists on staying vertical.
Any ideas would be gratefully received.
You're using outdated software and Spry is dead. Adobe abandoned Spry 8+ years ago. If you look at the date on those scripts, they haven't been touched in a dog's age which means Spry menus are unfit for use with modern browsers and mobile devices.
Rebuild your site responsively. Bootstrap is one option but not the only one.
