DESCRIPTION

Creates a ChoiceSetInput element that allows users to select from a list of options. This element can be rendered as a dropdown list, radio button group, or checkbox list depending on the Style and IsMultiSelect parameters.

ChoiceSetInputs are useful for collecting structured input from users, such as selecting preferences, categories, options, or making decisions from predefined choices.

NOTES

The ChoiceSetInput is one of the most versatile input elements in Adaptive Cards.

Style recommendations:

  • Use “compact” (dropdown) when you have many options or limited space
  • Use “expanded” (radio/checkbox) when you have fewer options (2-5) and want them all visible
  • Use “filtered” when you have a long list that users might need to search through

Remember that the value submitted will be the “value” property of the choice, not the “title” that is displayed to the user.
