Control submit button visibility using a fragment argument

[jingtang10]

Is your feature request related to a problem? Please describe.
At the moment we control the visibility of the submit button using styling. But perhaps we should control it a bit more explicitly using a fragment arguement. I worry that we're using a style attribute to control a very important functional behavior of the sdc library.

Describe the solution you'd like
Create a new fragment argument

@santosh-pingle you might still need to remove the style declarations in the style files.
