Hello. I want to make a website with a lot of categories. I would like it to start with a very broad category, such as countries, then it will display another drop down menu containing only states, then another drop down menu consisting of only states, then only streets.
Here is an example of the idea. First select the country, then another drop down will appear with only area, then a menu with only cities and then a menu with only universities.
Please take a look at the link above and if you can tell me how I can achieve this. Thanks a lot for the help. Also some guides would be helpful.
