class DialogUserSelector (*, name: str, label: str, optional: bool = False, value: Optional[str] = None, placeholder: Optional[str] = None)

The base class for JSON serializable class objects

Now you can easily populate a select menu with a list of users. For example, when you are creating a bug tracking app, you want to include a field for an assignee. Slack pre-populates the user list in client-side, so your app doesn't need access to a related OAuth scope.

https://api.slack.com/dialogs#dynamic_select_elements_users

Args

name

Name of form element. Required. No more than 300 characters.

label

Label displayed to user. Required. No more than 48 characters.

optional

Provide true when the form element is not required. By default, form elements are required.

value

Provide a default selected value.

placeholder

A string displayed as needed to help guide users in completing the element. 150 character maximum.
