Question

MySQL

Hello, I want to create for myself and practice in PHP and MySQL blog.
Now my task is: Create for the category, but not really! Heading titles will be added to the main nav, and on hover, a menu will drop out with a subcategory created for this particular heading.
The question is how to do it professionally?
Thanks in advance.
