hi,
i'm using comatose for a project. i have a tab navigation system where
i need to specify a id on the body and use a decendent css selector to
style the current tab.
#body_contactus #contactus {color: red;}
i have an instance variable on the layout
<body id="<%= body_id %>">
which i can then set on a view page <% body_id="contact_us" %>
whats the easiest way for me to specifiy an Id on the body from within
a comatose page??? is it using a drop or something. (i'm a comatose
newbie)
regards.

You can just stick it into the keywords field, and then create a
helper method to extract it from the page.
Example keyword
body_id:contact_us
def body_id( page )
...
end
We've used it for similar purposes several times (like excluding pages
from navigation, etc), and have yet to run into problems.
M@ will have to speak up, if he has other intentions for the keywords
attribute ;-)

You could just do something like this:
# application_helper.rb
def body_class( page )
page.keywords.scan(/body_class:([^ ]*)/).to_s
end
# layout file
<body class="<%= body_class( @page ) %>">
In your helper you could also navigate upwards in the page tree, until
you find a page with a body_class, but this should be enough to get
you started :-)

Oh, it was the body_id you were after, and not body_class.
The mechanics are the same though :-)
