Solution should be quite simple to this problem, but I can't make this 
system do what I want.. :)

I came to this solution(it doesn't work yet  ):
1) script in Site.SideBar calls
	(:pagelist fmt=#sidebar  name=Research.* :)
    so only pages from 'Research' group are selected;
2) script in Site.LocalTemplates
	[[#sidebar]]
	...
	(:if equal {$ReqPDir} {=$Group} )
	* [[{=$FullName}|+]]
	(:if:)
	...
	[[#sidebar]]
It checks if group of current page is the same as group of 
$RequestedPage. If it is, then second level of links of menu is shown.

I didn't find way to extract only group part of $RequestedPage while in 
Site.LocalTemplates. So I constructed this var (it should contain group 
of requested page, if any) in config.php:
$FmtPV['$ReqPDir'] = substr($FmtPV['$RequestedPage'], 1, 
strpos($FmtPV['$RequestedPage'], '.') - 1); //doesn't work!!!

Need help... Please correct me
