Hi @AvviCoder! I'm Dosu and I’m helping the dify team.

Multiline button labels using <br/> tags aren't supported in Dify right now. The frontend renders button text as plain text, so any HTML tags like <br/> are ignored and won't create line breaks. This is intentional—HTML rendering in buttons is disabled for security reasons (to prevent XSS attacks) and to keep the UI consistent. Even though the button CSS allows text wrapping, only plain text is used, so you can't force line breaks with HTML or Markdown syntax in button labels [source 1] [source 2].

There isn't a built-in workaround for true multiline buttons. If you just want long text to wrap naturally, that should work if you remove the <br/> tags and let the button width force wrapping. If you need explicit line breaks, that's not possible without a code change to allow HTML rendering in button labels, which is currently not recommended due to security concerns.

To reply, just mention @dosu.
