Thanks for your Help. Tom. What I want is a Selection drop down box and there will be only one switch box at start. Then the user need to click the selection 
box to prompt next selection box. I have tried to search the Internet, but I cannot find out any useful library to do it. I guess it is because English is my second language. So would you mind to give me some keywords to search the Internet. Thanks.
