Doing similar this kind of classification of goods, there is a problem, don't know how you do I chose the first brands such as HP, for example, that the following will display all the HP computer, I will choose the price below,,,, how can you know this time is in the HP price, under this category is selected after the HP, page refresh time, the second choice is how to remember under the level of classification, I want to use a cookie store, or incoming parameters in the url, don't know if this is common practice, also give advice or comments please
