need to load multiple views without stacking..

[eluser]ramabodhi[/eluser]
hey all.. as of right now im using dreamweaver templates to control the content on different areas of my site while mainaining consistency.... i haven't gotton into loading multiple views such as header, body, footer separately..

in the news area i have a sidemenu with different topics/areas such as headline, world, us, etc...
so my issue is, say im at the uri news/view/by_date/recent

and the function view($method = 'default', $style = FALSE) calls different models (which make different query's, looking say by date, or topic, etc)..

from here it loads the view with $data which has the news query results..

the problem arises when i click a different buttun, say im at by_topic/world and the button directs to by_topic/US.. it them makes the query to find news articles tagged with 'US', then loads the same view, just with different data.. and i use the code in the view to handle the data..

how do i do this without the views stacking.. the only solution ive cooked up is to use redirects set to refresh in my view() function which load a SEPARATE function to handle view loading.. it sounds complicated.. id rather be able to use multiple view loads in one function, as the page itself is a cyclic function...

really its probably due to the fact that im going about designing the page all wrong, any advice?
