Hi, i've installed mediawiki for a wiki project. now we have 4 sections on main page . like there are on wikipedia main page. Now as its done in wikipedia these 4 boxes are tables and update on date criteria. Now i want to do is to give some kind a navigation bar like drop down or paging. so when user selects page from drop down the all 4 pages are updated with relevant articles. to clear more. how the for parts of table can be updated . and how to put combo box ( which is already filled with page numbers / article topics) and which user selects any page from drop down all the 4 table rows are updated. any body help me . im new to media wiki searched alot. but didnot get any thing. or material or example. if i ve to made my extension then how ill write . means what is will the flow. how it will be pluged in the mediawiki and runs smoothly any article example. e-book from where i can read step by step. wating Noman
