Some institutions using CONSUL have expressed interest in this feature
since some of their tenants might already have their own domains.
We've considered many options for the user interface to select whether
we're using a subdomain or a domain, like having two separate fields,
using a check box, ... In the end we've chosen radio buttons because
they make it easier to follow a logical sequence: first you decide
whether you're introducing a domain or subdomain, and then you enter it.
We've also considered hiding this option and assuming "if it's got a
dot, it's a domain". However, this wouldn't work with nested subdomains
and it wouldn't work with domains which are simply machine names.
Note that a group of radio buttons (or check boxes) is difficult to
style when the text of the label might expand over more than one line
(as is the case here on small screens); in this case, most solutions
result in the second line of the label appearing immediately under the
radio button, instead of being aligned with the first line of the label.
That's why I've added a container for the input+label combination.
Note we're keeping this section's original design (which had one button
to add a new group which after being pressed was replaced by a button to
cancel) but we aren't using Foundation's `data-toggle` because there
were a couple of usability and accessibility issues.
First, using `data-toggle` multiple times and applying it to multiple
elements led to the "cancel" button not being available after submitting
a form with errors. Fixing it made the code more complicated.
Second, the "Add new group" button always had the `aria-expanded`
attribute set to "true", so my screen reader was announcing the button
as expanded even when it wasn't. I didn't manage to fix it using
`data-toggle`.
Finally, after pressing either the "Add new group" and "Cancel" buttons,
the keyboard focus was lost since the elements disappeared.
So we're simplifying the HTML and adding some custom JavaScript to be
able to handle the focus and manually setting the `aria-expanded`
attribute.
