I tried to adjust the navigation by padding/margin so that it can be very flexible. However, when I tried to set headerTabHeight to auto or blank, the un-selected navigation links will disappear?
Required? Not if you remove it from the template. It's used 4 different times in navigation to calculate a dimension. Modify the template to not use the value or at least remove it from the place its effecting your work negatively and then get on with life I suppose?
