[REQUEST] Examples for selecting from multiple options

[Adamtaranto]

Describe the solution you'd like
I am looking for a widget that will allow me to set a list of options for a user to choose from, as well as to set a default option.

Case 1: Allow a single option to be selected.
i.e. a set of radio buttons, or a drop down list.
Provide a visual indication of which option is currently selected.
Returns selected arg as string.

Case 2: Allow multiple selections.
Collection of Checkboxes or toggles would work here.
Visual indication of which options are currently selected.
Deselect option on second click..
Returns one more selected args as a list of strings.

Describe alternatives you've considered
I've considered creating separate widgets for each of the possible options for each multi-choice input arg of my script. This makes it messy to enforce single option selection (see case 1).

Is this feature present in other TUI products?
Not sure.
