Thanks for your reply Klas, I tried a module with search form, it shows the form as I want,
but one more problem started:
No search results found may be because of the url is not correct like :
http://bd.rnspublicity.com/index.php/component/cck/?sstate=&sdistrict=&scity=&category_of_item=&company_name=shri&cck=entry&search=free_listing&task=search
when I replace "component/cck/" with the menu title (directory) like the below url manually in the address bar, then it works :
http://bd.rnspublicity.com/index.php/directory?sstate=&sdistrict=&scity=&category_of_item=&company_name=shri&cck=entry&search=free_listing&task=search
Kindly shed some light...
