adding form info, buttons or drop down lists in page?

hello, the theme is great. i am messing around with it. i am trying to add some form info and some buttons in a page. what i am doing is making a page so someone can check a button and add some text and then submit to an email adress.

i see that you can do it from looking on the test site. but i dont know how to add them to a page.?

thank you for any help.
