Fair enough and thank you. The links took me to the site which I quoted in my question - that is the one which said:
-hidden
When set to a true value, causes the resulting tab to be hidden from view; can later be set to a false value to force the tab to be visible again."
However when try to use -hidden as next
$tabbed_frame{$dynatab_name}->configure(-hidden => 1);

I got the error 
Tk::Error: Can't set -hidden to `1' for Tk::Frame=HASH(0x20f90157e48):
+ unknown option "-hidden" at C:....

I would love to know what to do so stop getting this error.
