Some sort of folding menus

[SkyFrontier]

I've asked Marco on this being or not possible - missing several updates on XY this year and the resource could be already implemented, but it seems it is not.

So...

"Group 1"
"autorefresh|:autorefresh" copytext ":autorefresh";
"back|:back" copytext ":back";
"backupto|:backupto" copytext ":backupto";
"bfop|:bfop" copytext ":bfop";
"Group 2"
"browsenetwork|:browsenetwork" copytext ":browsenetwork";
"calcfosi|:calcfosi" copytext ":calcfosi";
"cat|:cat" copytext ":cat";
"cks|:cks" copytext ":cks";
"Group 3"
"clip|:clip" copytext ":clip";
"closetab|:closetab" copytext ":closetab";

could be shown as
"Group 1"
"Group 2"
"Group 3"

and after "Group 3" clicked, the
"clip|:clip" copytext ":clip";
"closetab|:closetab" copytext ":closetab";

part is shown.

Can this be implemented, Don?
