Not sure whether this belongs in SP, template or Helix, but I'm trying to add content below the menubar on this link and update the font colour of the menu itself...

Am having a few issues.

1. Where can the type colour of the menu text be updated? Its ignoring the colours I specify in Rhino styles.
2. Search box - I moved the Rhino top layer fields down below the menubar and added a standard Joomla search to one of the top positions. It just appears overlapping the menu text, rather than underneath. But...
3. When I create a SP module and put the two contact and join buttons you can see in the link above into the top position, they appear correct, but won't align full right and seem to disappear when I try to make the section and column they are in full width in SP.
4. And then when I try to add the search field in there via inserting a Joomla module in via SP, then it shoves the buttons far right stacked and does not show the search at all.
5. And no matter if I assign page links to the buttons, they do not work when clicked in the front end and do nothing.
6. How also can the default colours of the buttons be changed, both there and elsewhere in the site? eg primary, secondary, info etc? Is that just via CSS hacks?

I hope that makes some sense. Is there any tutorial on editing the header area? I just seemed to understand from the forum that adding another line below the menu was a matter of assigning modules to template positions, but it just doesn't seem that straightforward to get things to align and work in harmony with the menu.

Thanks, Leo
