cre loaded page modification.

I would like to have a method of showing a better product index page for certain categories on my cre loaded web page. on certain categories from the main menu I would like to show a nested list such as the one at [login to view URL] I do not want this format to be shown for every category from the main menu, but would like an admin function to allow me to turn this on or off for pages or categories i choose. for example. if you where to go to the page [login to view URL] I would like that page to list like [login to view URL] showing top category, and all products below that category, and link to the relevent page. priority will be given to those bidding a sensible figure for the job, I suspect this wouldnt be to hard for a skilled coder. I will provide colours for header tables, and would expect that the text matches the sites current CSS style. If my requirements are not clear please PM me. ************************ Only bidders with a good reliability rating will be considered. ************************ ************************ Only sensible bids will be considered ************************ ************************ I am a reliable and fast payer to the right person. ************************ I do not want an exact copy of [login to view URL], would like a unique design principle, however the theory must be the same. additionaly the job requires adding osCsid string to the search box in the header area of the site.
