Build Sign up form with selections, radio button and checkbox

I have skimmed through the docs but i dont seem to see a guide on how to add form elements like selections, radioButtons and checkboxes to my app

Those three you mention can be easily built using our Selection API. If you take a look at our Examples, you’ll find several that resemble form elements: Custom toggle control, Radio buttons and others. There’s also a massive example on using the Selection API in general.

Hope this helps!
