A button can be used to group related options (multi-select & single select), inspired by React Material UI.

pip install streamlit-toggle-button-set

import streamlit as st
from toggle_button_set import toggle_button_set

outcome = toggle_button_set(
    button_list=['a', 'b', '1', '2'],
    default=['a', '1'],
    color="primary",
    size="large",
    exclusive=False,
    use_container_width=False
)

st.write(outcome)

• button_list

• default = [] - must be a subset of button_list, these options are automatically selected upon boot.
• color = "standard" - The color of the button when it is selected, options includes 'standard', 'primary', 'secondary', 'error', 'info', 'success' and 'warning'.
• size = "medium" - The size of the component, options includes 'small', 'medium' and 'large'.
• exclusive = False - forces only one item to be selected from button_list.
• use_container_width = False - will make the component take up the full width of its container.
