Create a list of companies based that match dropdown selection

I am new to ExcelForum. I have the attached excel spreadsheet of 150 semiconductor design companies that design one chip or a combination of 40+ chips. I would like to be able to have a easy way for a user to be able to list companies that design a selected type of chip by using something like dropdown list of types of chips that will generate a list of companies that design that type of chip. My ultimate goal is to put this online on a webpage that will allow a user to list companies that design microprocessors for example (e.g., AMD and Intel).
