3 Tier Toggle

[MatileM]

I am wanting to design a FAQ page that features a toggle option that slides down. Here is how I would like it to be setup:
Category A

Question 1

Answer 1

Question 2

Answer 2
Category B

Question 1

Answer 1

Question 2

Answer 2

I would like it so that when you click on 'Category A' a list of questions will slide down and from there you can select a question and the answer will slide down. I have found toggles online that use CSS and Javascript, but they are only 2 level and I need a 3 level and I am not sure how to edit those to meet my needs. Could you please help?

Here is the code:


<style type="text/css">



.dhtmlgoodies_question{ /* Styling question */
/* Start layout CSS */
color:#FFF;
font-size:0.9em;
background-color:#324BC3;
width:430px;
margin-bottom:2px;
margin-top:2px;
padding-left:2px;
background-image:url('images/bg_answer.gif');
background-repeat:no-repeat;
background-position:top right;
height:20px;

/* End layout CSS */

overflow:hidden;
cursor:pointer;
}
.dhtmlgoodies_answer{ /* Parent box of slide down content */
/* Start layout CSS */

background-color:#D5E1F0;
width:400px;

/* End layout CSS */

visibility:hidden;
height:0px;
overflow:hidden;
position:relative;

}
.dhtmlgoodies_answer_content{ /* Content that is slided down */
padding:1px;
font-size:0.9em;
position:relative;
}

</style>
