How to add page content and webform as tab in a page? I'm using drupal 7 and I have a content type "service".  

And I have a enquiry page, built with webform with following fields:


Name 
Email
Service
Message


In each service page, I would like to have a tab for page content, a tab "Enquiry", with the enquiry webform in the tab.

For service field, I would like it to show page title as default.

Is there any way I can do it?
There are two ways to do that : 


Write a custom module and create a menu path "node/%node/enquiry" and return your enquiry form programmatically. In hook_menu you can set type = MENU_LOCAL_TASK that will display the path as tab.
You can create a view page that displays webform and select the menu Menu tab under menu setting. Path of page should be node/%/enquiry, so that It will create a tab on node/% page. Screenshot for the second method :
