Hello Anuradha,
First you have to create one going to document properties, on the general tab there's a button that says something like Alternate State. There you can create your first alternate states.
Once you created that state, when you add a new object or with the others you have created you can right click on them, click on Properties, and on general tab on the right on the text box where you write the window title you will be able to see Alternate States, there you can choose the one you created.
Regards.
