I’m using the smartmenus which works fine but the issue I’m having an issue when I rollover the main navigation – the submenu links appear automatically underneath the main dropdown menu. I have a link below – as soon as the page loads > hover over Celebrations and you will see the issue.
starting at line 4297 you have the following rule:
.nav > li:hover ul {
display: block;
}
This rule is not part of the original Bootstrap CSS (even for v3.0.0 that you seem to be using) and I am not sure why it’s there for you, but basically you will need to remove it and it should all work fine.
