//
// A Clear option and a Multiple Selection indicator are populated in the Dropdown List as appropriate.
//
// Supports "pseudo" OPTGROUPS; if OPTIONs are indented (THIS IMPLEMENTATAION: supports one level),
// selection of an OPTGROUP item in the Dropdown (which is normally not permitted with OPTGROUP...)
// selects all indented OPTIONS beneath it (a bit more intuitive, no??)
//
// Tested for Opera 8.1, Internet Explorer 6, and FireFox
