How do I create a multiline bot response in Rasa Core?

Question

Can anyone help how to get bot responses in multiple lines. Also how to get bullets in the Bot responses. I tried with >, * , enter key and also. Nothing seem to work. Does Rasa response templates support HTML tags?

Answer 1

The visualization of the message depends on the output channel which you are using. Hence, it should be possible to provide HTML tags in your bots answers as long as your output channel can then correctly render it. For a simple newline, please try adding a "\n" in your messages, e.g.:

utter_message:
  - text: "First line\nSecond line\Third line"

You can also have a multiline string in your yaml file which then results in a string containing newlines (see here for examples). The block below is the same as the example above:

utter_message:
    - text: >
        First line
        Second line
        Third line

To include bullets, you could simply add the unicode character of a bullet, e.g.:

utter_message:
    - text: >
        • First line
        • Second line
        • Third line
