GoogleAppsCardV1SelectionInput class

A widget that creates one or more UI items that users can select.

For example, a dropdown menu or checkboxes. You can use this widget to collect data that can be predicted or enumerated. For an example in Google Chat apps, see [Add selectable UI elements](/workspace/chat/design-interactive-card-dialog#add_selectable_ui_elements). Chat apps can process the value of items that users select or input. For details about working with form inputs, see Receive form data. To collect undefined or abstract data from users, use the TextInput widget. [Google Workspace Add-ons and Chat apps](https://developers.google.com/workspace/extend):
