Parameters

Parameter	Description
showhide	Set to "left" (without speechmarks) to switch the [show/hide] link's position from the righthand end of the titlebar (default) to the left.

title	Text shown in titlebar.
titlestyle	CSS styles to apply to the titlebar (e.g. `\|titlestyle=border:1px solid lightgrey;` to produce a border around it; `\|titlestyle=background:color;color: inherit` to set its background color to color ; `\|titlestyle=text-align:[center/right];` to switch its text (title)'s alignment from left to center or right; etc.).
bg1	Background color for titlebar; defaults to transparent. May be overridden if titlestyle includes anything that changes the background.
