Use the SectionFlagIsSet macro in Include\Sections.nsh (!include "Sections.nsh") along with the SF_SELECTED flag to check if a certain section is selected. For example:

!insertmacro SectionFlagIsSet ${section1} ${SF_SELECTED} selected notselected
selected:
  MessageBox MB_OK "section 1 is selected"
  Goto done
notselected:
  MessageBox MB_OK "section 1 is NOT selected"
done:

In my components page, some sections are disabled depends on detection if other programs installed on this computer. User may install all components which are enabled or only one enabled component. I don't allow user leave components page if nothing is selected.

comm@nder21 code works fine for me. Thanks a lot.
