Thanks for the help but please see my comments in bold
- I will first go to design mode and will see if my components are included in that parsys
answer - yes they are included
- if you have two parsys on page, like sightly and jsp
answer - all the parsys are jsp.
- also check the allowed parents or children property
answer - all components are allowed and are able to see in left rail.
- try to click on parsys on edit mode and click on + sign. and see if you see the component
answer - hen clicking on edit mode and select the parsys the + sign (tool bar as below)is not appearing 
need more input on this as the problem is not yet solved
Thanks
