Vague question: What is a good place to read up on current web technology and trends? I feel like I know the languages, but I don't know what people are doing with them.
Specific question(s): My current page has a box for a product number. What I want to happen is the user clicks the text input box and an overlay box comes up (like the new login on these forums) with a dropdown containing a list of product categories. The user picks a category, and another dropdown appears/populates with the products from that category. When a product is selected from that dropdown, the product number of the selected product populates the initial textbox.
Don't need any code, just help defining my goal - google is useless if you don't know what to call things. 8(
