Displaying interfaces

Hi All, 

I have a requirement in my project, 

I have 16 diffrent interfaces, which need to be displayed based on condition, 

ex: if ruleinput(id) value is 1 ,then 1st interface should get displayed. 

           if id=2, 2nd interface should get displayed. like that I have to display 16 interfaces vased on id value, 

can you please help me,how can i achive this other than using ifelse conditions?

Thanks

Divya
