Inserts a header line with navigation AND ability to "collapse it".
The following parameters are recognized:
The unique ID to associate with the header line (the area ID will be assigned: ID + "-area" and the icon will be assigned: ID + "-icon")
The text to appear on the header line.
The header level to use (defaults to "h2").
The initial "collapse" state. Pass "none" to initially hide, or "block" to initially show (any CSS "display" value is legal).
This macro is defined as:
<script@htmlAttr("type","text/javascript")> setNavLinkHome("@topDir()/index.cgi","","@exitAnchor()"); addCollapsibleHeader("@param(1)","@param(0)","@param(3)","@fnb("@param(2)","h2")","@imageDirUrl()/"); @define("wuiHtmlHeaderAnchor","@param(0)","now") </script> <div @htmlAttr("id","@param(0)-area") @htmlAttr("style","display: @fnb("@param(3)","block");")>
