Hey everyone 👋

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.

### Keywords (SEO)

Hope that helps! 😊

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. 😊 @fede.bubble
