My front page is basically a view that lists teasers of node type article. How can I show a specific submenu and mark one item in this submenu as active (+ its parent) when
1) the front page is opened or
2) any article is opened?
I know 2) can be done with the module "Context Active Trail" and "Context UI", but I want to do it without a module and I think the module can't do 1) anyway.
