In the Config Tab of the Thing Description Interface the user can select the option 'raw' or 'form-fields'.
The option 'form-fields' is not yet implemented.

What should the option form-field look like?
It should basically show all options of the config in key-value pairs and a checkbox to 'active' them (include them into the config).

Similar to this, but with another field on the left, which is checkbox to include them.
