I have been using Dreamweaver to create my website. I was trying to insert a dropdown menu with the code listed on this site and when i paste it into the editor with all my information it messes up the layout of my page but when I preview it in my browser it seems to be fine. Then I noticed that in editor view it hilights it in yellow and says the tags are wrong. Is anyone familiar with this program and why this might be happening?

Thanks,
Kristen
