collapse-o-matic plugin

I want to have a plugin for FAQ.
I test severals but all have problems for me.

– only 5 questions
– do not work
– strange lay-out

Now I found an simple plugin that also works with pull down effect.

But the problem is the white spaces. I search on internet and find the sollution. Problem I do not understand it.

What do I had to do with the answer from competetowin

There are two codes, the first code I had to put in the text (like shortcode), but where do I put the second one.

div#menuspacefix br {display:none;}
