Hello again good sirs,

I am building a webstore that has 36 different BuyNow modules on 36 unique pages, in order to account for the wide range of product my company has for sale. Due to the complexity, I can not simply use the category module for my store navigation, as I will need to create many custom links in those categories.

I have found that Passing the CategoryID in the querystring is a great solution to this problem, and I have successfully built my own custom shopping navigation!

However, I have run into one problem setting up this navigation to be user friendly. In order to illustrate my problem, lets say for example I have two unique buynow modules set up. They would be on pages

www.test.com/guitars

www.test.com/drums

Each buynow module has two categories. Soo all categories between stores would be Guitars1(categoryid=1), Guitars2(categoryid=2); Drums1(categoryid=3), Drums2(categoryid=4);

Both buynow pages have the exact same navigation on the left hand side, which I have provided via an HTML module, so it is easy to switch between the stores and categories. The menu structure is as follows.

link 1 = www.test.com/guitars.aspx

link 2 = www.test.com/guitars.aspx?categoryid=1

link 3 = www.test.com/guitars.aspx?categoryid=2

link 4 = www.test.com/drums.aspx

link 5 = www.test.com/drums.aspx?categoryid=3

link 6 = www.test.com/drums.aspx?categoryid=4

Now for the problem. I wish for my navigation to show which link is currently selected. This is easy to do for links 1 and 4, as they are unique pages on my site. I can simply change their css class on the page. However,  I need links 2,3,5,6  to do the same. 

I noticed that the category module has this issue solved by making the link chosen a "selected node", so even though the user remain on the same buynow page, switching categories within that buynow page is shown in their shopping menu with a highlighted link.

Is there a relatively simple way for me to implement a similar feature with my custom menu? I simply can not use the category module for my navigation :(

Hope this made sense. Thanks!

Alex
