[Typo3-dev] Problem in implementing menu in the subpages.

[typo3(eng)]

Sir,

I am working in typo3. I am facing a problem in implementing the menu in the
subpage.
Whenever i am clicking any sub link from a menu in the main page i am moving
to the subpage but the subpage is showing only the clicked sublink and the
links under it if present.
The parent links are disappearing.
I am in bit problem since it is bit urgent. Please help me to get out of
this problem.Waiting for your kind help and response.
