Notice Element - expand subtitle on-click

When adding the notice element, builders have the option to ‘hide subtitle’. Not sure what the intended use of it is (builder internal note?) but it would be great to instead have users click to expand/collapse the subtitle, maybe a little arrow or expand […] icon to indicate that a user can click to read more detail about the notice. Then users who already know what the alert means don’t need to have a bunch of subtitle text taking up space.

In my case, I’ve added a notice as an instructional element to a form (a key indicating what the various statuses mean). Would be great for users to be able to show/hide the subtitle, i.e. the details of the notice.

This is actually a (potentially) subtle design thing, and it should probably be set by default

But the alignment is marginally different when there’s no subtitle

We can probably remove it.

Great idea to allow us to toggle the notice details though!
