Display a single-line text input widget.

Function signature[source]

st.text_input(label, value="", max_chars=None, key=None, type="default", help=None, autocomplete=None, on_change=None, args=None, kwargs=None, *, placeholder=None, disabled=False, label_visibility="visible")


label (str)

A short label explaining to the user what this input is for. The label can optionally contain Markdown and supports the following elements: Bold, Italics, Strikethroughs, Inline Code, Emojis, and Links.

This also supports:

  • Emoji shortcodes, such as :+1: and :sunglasses:. For a list of all supported codes, see https://share.streamlit.io/streamlit/emoji-shortcodes.
  • LaTeX expressions, by wrapping them in "$" or "$$" (the "$$" must be on their own lines). Supported LaTeX functions are listed at https://katex.org/docs/supported.html.
  • Colored text and background colors for text, using the syntax :color[text to be colored] and :color-background[text to be colored], respectively. color must be replaced with any of the following supported colors: blue, green, orange, red, violet, gray/grey, rainbow. For example, you can use :orange[your text here] or :blue-background[your text here].

Unsupported elements are unwrapped so only their children (text contents) render. Display unsupported elements as literal characters by backslash-escaping them. E.g. 1\. Not an ordered list.

For accessibility reasons, you should never set an empty label (label="") but hide it with label_visibility if needed. In the future, we may disallow empty labels by raising an exception.

value (object or None)

The text value of this widget when it first renders. This will be cast to str internally. If None, will initialize empty and return None until the user provides input. Defaults to empty string.

max_chars (int or None)

Max number of characters allowed in text input.

key (str or int)

An optional string or integer to use as the unique key for the widget. If this is omitted, a key will be generated for the widget based on its content. Multiple widgets of the same type may not share the same key.

type ("default" or "password")

The type of the text input. This can be either "default" (for a regular text input), or "password" (for a text input that masks the user's typed value). Defaults to "default".

help (str)

An optional tooltip that gets displayed next to the input.

autocomplete (str)

An optional value that will be passed to the <input> element's autocomplete property. If unspecified, this value will be set to "new-password" for "password" inputs, and the empty string for "default" inputs. For more details, see https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/autocomplete

on_change (callable)

An optional callback invoked when this text input's value changes.

args (tuple)

An optional tuple of args to pass to the callback.

kwargs (dict)

An optional dict of kwargs to pass to the callback.

placeholder (str or None)

An optional string displayed when the text input is empty. If None, no text is displayed.

disabled (bool)

An optional boolean, which disables the text input if set to True. The default is False.

label_visibility ("visible", "hidden", or "collapsed")

The visibility of the label. If "hidden", the label doesn't show but there is still empty space for it above the widget (equivalent to label=""). If "collapsed", both the label and the space are removed. Default is "visible".


(str or None)

The current value of the text input widget or None if no value has been provided by the user.


import streamlit as st

title = st.text_input("Movie title", "Life of Brian")
st.write("The current movie title is", title)

Text input widgets can customize how to hide their labels with the label_visibility parameter. If "hidden", the label doesn’t show but there is still empty space for it above the widget (equivalent to label=""). If "collapsed", both the label and the space are removed. Default is "visible". Text input widgets can also be disabled with the disabled parameter, and can display an optional placeholder text when the text input is empty using the placeholder parameter:

import streamlit as st # Store the initial value of widgets in session state if "visibility" not in st.session_state: st.session_state.visibility = "visible" st.session_state.disabled = False col1, col2 = st.columns(2) with col1: st.checkbox("Disable text input widget", key="disabled") st.radio( "Set text input label visibility πŸ‘‰", key="visibility", options=["visible", "hidden", "collapsed"], ) st.text_input( "Placeholder for the other text input widget", "This is a placeholder", key="placeholder", ) with col2: text_input = st.text_input( "Enter some text πŸ‘‡", label_visibility=st.session_state.visibility, disabled=st.session_state.disabled, placeholder=st.session_state.placeholder, ) if text_input: st.write("You entered: ", text_input)
