User Input Widgets

Capture clicks, selections, text, files, and slider values in Streamlit

Widgets let users interact with your app and provide data to your Python code.

Buttons

Use a button when you want an action to happen after a click.

import streamlit as st

if st.button("Click me"):
    st.write("Button clicked")

Text input and text area

Use text fields for short and longer free-form input.

import streamlit as st

name = st.text_input("Your name", placeholder="Amit Patel")
notes = st.text_area("Notes", height=120)

Selectbox, radio, and checkbox

These widgets are useful for choosing one option or toggling a simple setting.

import streamlit as st

city = st.selectbox("Choose city", ["Mumbai", "Delhi", "Bengaluru"])
gender = st.radio("Gender", ["Male", "Female", "Other"])
agree = st.checkbox("I agree")

Multiselect

Use multiselect when users should be able to choose more than one value.

import streamlit as st

skills = st.multiselect("Select skills", ["Python", "SQL", "Machine Learning"])

Number input and slider

These widgets are ideal for numeric inputs.

import streamlit as st

age = st.number_input("Age", min_value=0, max_value=120, value=25)
rating = st.slider("Rating", min_value=1, max_value=10, value=5)

File uploader

Allow users to upload CSVs, images, or other files.

import streamlit as st

uploaded_file = st.file_uploader("Upload a file", type=["csv", "png", "jpg"])

Date and time inputs

Use date and time widgets for scheduling and filtering.

import streamlit as st

birthday = st.date_input("Select birthday")
meeting_time = st.time_input("Select time")
