Thanks - it could be a problem my end or something that intermittently happens but some of the dropdown toggle elements e.g. .navbar27_dropdown-toggle need to be full height in the navbar container. Ones like in Navbar 14 don't I believe because there is an overlap of the dropdown menu. I have found that sometimes I get navbar14 height toggles in the navbar27 type nav bars. I say this could be my end as I realise that for the nav I was building yesterday (when I was going to ask about this) I was mixing and matching some elements (using multiple different dropdown menu types for a single nav) - but I have had this problem before when I don't believe I was doing that.
