My current website product page's side bar couldn't display the list of relative section of categories. (such as if I click on a specific product section, then I wish the side bar widgets could show all the relative model of product that only under that product section by classifying in other category like brands & model) 

Please kindly see attached 2 picture for example.

For example of picture 1:If I select "Air Filter" for " By Product" category in menu, then I want the side bar display all relative product that only for Air Filter. Therefore, customers could easy find all Air Filter products only in other classification of categories like "By Brand", "By Model", "Combo/New Arrivals/On sale Now".

For example of picture 2: if I select the "Briggs & Stratton" for "By Brand"category in menu, then I want the side bar display all relative product that only for  brand of Briggs & Stratton. Therefore, customers could easy find all Briggs & Stratton products Only in other classification of categories like "By Model", "By Product", "Combo/New Arrivals/On sale Now".

Thank you again!

Hi Gregor,

I thought maybe some other people whom looking at this website might have better solutions.

Thanks a lot. I'll look for the plug-in on my own.
