You'll want to remove the margin of the pre used for parameter name.

Show a message when no description is available. Differentiate between services known to HA and ones that are not known (known services can still have no description).

Show a message that the user has to pick a service/domain when none selected.

Soo, in the future maybe we should allow people to fill in values directly next to the description 👍

@balloob should be good to go

[balloob]

One final change: when selecting a new domain, can we auto select the first available service? (means we can also get rid of no service selected)

Ok to merge when comment addressed 🐬
