Configuration

You use CSS(The part between <STYLE type="text/css"> and </STYLE>) to configure the colors and fonts used in the slide in pane. Look at the comments there for more help.

Javascript variable are used to specify if:

Sliding should be used or not. If it's not used, it will pop out instantly.
The speed of the sliding effect
The width of the panel
If your main content should be pushed to the right when sliding

This is the default settings for these variables:
var panelWidth = 150; // Width of help panel
var slideSpeed = 15; // Higher = quicker slide
var slideTimer = 10; // Lower = quicker slide
var slideActive = true; // Slide active?
var initBodyMargin = 0; // Left or top margin of your tag (left if panel is at the left, top if panel is on the top)
var pushMainContentOnSlide = true; // Push your main content to the right when sliding
var panelPosition = 0; // 0 = left , 1 = top

Update content of left panel dynamically

You can update the content of the left panel by calling the function setLeftPanelContent. Example:
<A href="#" onclick="setLeftPanelContent('Hello <b>There</b>');return false">Show help
