Configurable Toolbar Features

Oct 13, 2025 by wbrum.org 48 views

Introduction

Streamlit's st.chat_message component provides a simple and intuitive way to display chat messages in your application. However, the current implementation lacks the flexibility to customize the toolbar actions, limiting the developer's ability to respond to user interactions. This issue aims to address this limitation by introducing a configurable toolbar for st.chat_message, enabling developers to implement custom actions similar to those found in tools like ChatGPT and Google Gemini.

Problem Statement

The current st.chat_message component provides a basic toolbar with limited actions, such as sending a message or deleting the chat. However, this is not sufficient for applications that require more complex interactions, such as:

Responding to user messages with custom actions
Implementing chat message actions similar to those found in popular chat tools
Providing a more engaging user experience through customizable toolbar actions

Solution Overview

To address the limitations of the current st.chat_message component, we propose introducing a configurable toolbar that allows developers to customize the actions displayed in the toolbar. This will enable developers to implement custom actions, such as:

Responding to user messages with custom actions
Implementing chat message actions similar to those found in popular chat tools
Providing a more engaging user experience through customizable toolbar actions

Configurable Toolbar Features

The proposed configurable toolbar will provide the following features:

Customizable actions: Developers will be able to add custom actions to the toolbar, such as responding to user messages or implementing chat message actions.
Action configuration: Developers will be able to configure the actions displayed in the toolbar, including the action text, icon, and behavior.
Event handling: Developers will be able to handle events triggered by user interactions with the toolbar actions, such as clicking on an action or hovering over an action.

Implementation Details

To implement the configurable toolbar, we will introduce a new st.chat_message parameter, toolbar_actions, which will accept a list of custom actions. Each action will be represented by a dictionary containing the action text, icon, and behavior.

Here is an example of how the toolbar_actions parameter might be used:

import streamlit as st

# Define custom actions
actions = [
    {"text": "Respond", "icon": "👍", "behavior": "respond"},
    {"text": "Delete", "icon": "🚮", "behavior": "delete"}
]

# Create a chat message with custom toolbar actions
st.chat_message("Hello, how are you?", toolbar_actions=actions)

In this example, the toolbar_actions parameter is used to define a list of custom actions, including "Respond" and "Delete". The behavior parameter is used to specify the action to be taken when the user interacts with the action.

Benefits and Use Cases

The configurable toolbar for st.chat_message will provide several benefits and use cases, including:

Improved user experience: The customizable toolbar will enable developers to provide a more engaging user experience through customizable actions.
Increased flexibility: The configurable toolbar will allow developers to implement custom actions, such as responding to user messages or implementing chat message actions.
Enhanced chat functionality: The configurable toolbar will enable developers to provide more advanced chat functionality, such as custom actions and event handling.

Conclusion

In conclusion, the configurable toolbar for st.chat_message will provide a more flexible and customizable way to display chat messages in Streamlit applications. By introducing a configurable toolbar, developers will be able to implement custom actions, such as responding to user messages or implementing chat message actions, and provide a more engaging user experience through customizable toolbar actions.

Future Work

Future work on this issue will focus on implementing the configurable toolbar and providing a more comprehensive set of features and use cases. This will include:

Implementing the configurable toolbar: We will implement the configurable toolbar and provide a more comprehensive set of features and use cases.
Providing additional documentation: We will provide additional documentation on how to use the configurable toolbar and implement custom actions.
Testing and validation: We will test and validate the configurable toolbar to ensure it meets the requirements and provides a seamless user experience.
