I have discovered that IE has an issue displaying the drop down menus in Wordpress. In my case I'm using the Education Child theme, but this really has nothing to do with the theme.
The same iframe pages display fine in Firefox and Chrome and I suspect in Safari as well.
Here is a sample of one of my site pages with this issue http://www.bllhschool.org/uat/wordpr...-health-update
Keep in mind the problem only shows itself in IE.
I have tried using z-index to fix the issue but it didn't help.
If anyone can tell me how to fix this easily it would be greatly appreciated.
