I am wondering how to make my website's home page have a only 3 drop down menus; when someone clicks a topic from the first drop down menu, I want the second drop down menu to only display sub categories from the first category chosen. After they select this, the third drop down menu will display all the sub categories of the sub categories. At the very right, viewers will click search and it will show a list of all the posts that are within the last sub category underneath this entire box. What is the coding I would need for this. Please explain the methods as well as I am a newbie. Thank you so much!
