I am new to bootstrap. I have a page set up with a bootstrap grid and form controls (example below) .
I have two sets of user input controls, applicable in two different scenarios.
if only set of first input controls is applicatble to a user, I would like to hide the second col, and
expand first column to take the full width inside the container?
how can i achieve this
.... <-- first set of input controls -->
... <-- second set of input controls -->
