    No, I just need after I select from the drop down to display the options for each of post type... and only after I set up all needed options after that if I click save button the options to be saved...
    
    Now for example I can see the Portfolio options only after I click the save button, but I need them to see after I select from the drop down - without clicking the save...

  Okay cool I have created plugin for my theme where it will display normal post and custom post type recent posts and it is working completely fine without any trouble.
  
  Here is the full code.
  
  Please do not use mediaplus change to your theme name. That's my theme name :)

  Only one thing forgot to mention that once you select any option from dropdown and after save it will selection will jump back to the first option. But at the front end it will display the option what you have selected and saved. If you find any solution for it pls share with me too.

    This is not what I need... My widget works cool with extracting the posts from post types, my problem is in the backend...
    
    Is there anyone who can help me?

    Okay I got what you mean. You mean to display sub option forms as per selection into dropdown options. That also I have done for my metaboxes. Just provide me your code if possible so I can make it works for you or I can post the update in the evening.
