Hey everyone :waving_hand:

I just used some custom code (thanks to AI) to customize the bubble Multiline Input into a Slack-like input. So it is better for chat functionality. You can copy it for FREE.

Goal

Override Bubble’s default multiline input to send on Enter and use Shift+Enter for new lines. Simple Slack-style chat behavior.

Problem

By default, Bubble’s multiline input behaves like this:

  • Enter → creates a new line
  • No built-in way to send a message on Enter

For chat-style apps, this isn’t ideal.

Solution

This enables Slack-style behavior:

Desktop

  • Enter → send message
  • Shift+Enter → new line

Mobile

  • Enter → new line
  • Button → send

Setup (Important)

Assign these IDs in Bubble:

Multiline Input ID: chatInput
Submit Button ID: submitButton

Make sure your submit button workflow:

  • sends/saves the message
  • resets the input

Why this matters

If you’re building:

  • chat apps
  • AI interfaces
  • messaging features

Users expect Enter-to-send behavior.

I actually think Bubble could make this an option for the MultiLine input. Right now it’s just not very useful. This makes it much more useful. :blush: @fede.bubble
