title: Creating Dependent Dropdown list
body: <p>I am trying to create a 3 layered drop down list menu for my automotive company, I need each drop down menu to be dependent on the previous selected option. </p>
  
  <p>For example: 
  <strong>CAR MAKE:</strong> BMW
  <strong>BODY STYLE:</strong> 3 Series
  <strong>ENGINE:</strong> S52 3.2L I6</p>
  
  <p>I don't even know what to search for, or how to implement it(Javascript, PHP, JSON, Ajax etc), can someone point me in the right direction on which would be the easiest way to go about building such a drop down menu? Any help is greatly appreciated!</p>
