streamlit-pills 💊

A Streamlit component to show clickable pills/badges.

This custom component works just like st.selectbox but shows the options as clickable pills. It's nice to show the user upfront what they can select, without going through a dropdown.

Installation

pip install streamlit-pills

Usage

from streamlit_pills import pills
selected = pills("Label", ["Option 1", "Option 2", "Option 3"], ["🍀", "🎈", "🌈"])
st.write(selected)

See the demo app for a detailed guide!

Development

Note: you only need to run these steps if you want to change this component or contribute to its development!

Setup

First, clone the repository:

git clone https://github.com/jrieke/streamlit-pills.git
cd streamlit-pills

Install the Python dependencies:

poetry install

And install the frontend dependencies:

cd streamlit_pills/frontend
npm install

Making changes

To make changes, first go to streamlit_pills/__init__.py and make sure the variable _RELEASE is set to False. This will make the component use the local version of the frontend code, and not the built project.

Then, start one terminal and run:

cd streamlit_pills/frontend
npm start

This starts the frontend code on port 3001.

Open another terminal and run:

cp demo/streamlit_app.py .
poetry shell
streamlit run streamlit_app.py

This copies the demo app to the root dir (so you have something to work with and see your changes!) and then starts it. Now you can make changes to the Python or Javascript code in streamlit_pills and the demo app should update automatically!

If nothing updates, make sure the variable _RELEASE in streamlit_pills/__init__.py is set to False.

Publishing on PyPI

Switch the variable _RELEASE in streamlit_pills/__init__.py to True. Increment the version number in pyproject.toml. Make sure the copy of the demo app in the root dir is deleted or merged back into the demo app in demo/streamlit_app.py.

Build the frontend code with:

cd streamlit_pills/frontend
npm run build

After this has finished, build and upload the package to PyPI:

cd ../..
poetry build
poetry publish
