[thelist] Adding an indicator to collapsable content

[Dave]

List,

    The Situation:
    I have succeeded in getting content to show and hide using Java 
Script and CSS. I would like to extend the idea just a little further by 
adding a small indicator by the link which activates the show and hide 
script.
    All I want is a "+" beside the link when the content is hidden, and 
a "-" when it is shown. Like so:
    In hidden state:
+ Click here to see stuff
    In shown state:
- Click here to see stuff
    stuff
    stuff
    stuff

    The Problem:
    I have no idea how to do this. The show/hide action I'm using was 
taken from a tutorial on the net, and it was only by asking questions 
about it here that I got it to work.

    What I've tried so far:
    I looked again on the net for a more robust script, but while I 
learned that what I was looking for was termed "collapsible content", 
and so how to make remote show and hides, I did not see a script that 
included an indicator like I am looking for.

    The Question:
    Can anyone recommend a script that does what I describe?

    Any help much appreciated.
