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 that disables the text input if set to ``True``. The default is ``False``. label_visibility : "visible", "hidden", or "collapsed" The visibility of the label. The default is ``"visible"``. If this is ``"hidden"``, Streamlit displays an empty spacer instead of the label, which can help keep the widget alligned with other widgets. If this is ``"collapsed"``, Streamlit displays no label or spacer. Returns ------- str or None The current value of the text input widget or ``None`` if no value has been provided by the user.

Parameters ---------- label : str A short label explaining to the user what this input is for. The label can optionally contain GitHub-flavored Markdown of the following types: Bold, Italics, Strikethroughs, Inline Code, Links, and Images. Images display like icons, with a max height equal to the font height. Unsupported Markdown 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"``. See the ``body`` parameter of |st.markdown|_ for additional, supported Markdown directives. For accessibility reasons, you should never set an empty label, but you can hide it with ``label_visibility`` if needed. In the future, we may disallow empty labels by raising an exception. .. |st.markdown| replace:: ``st.markdown`` .. _st.markdown: https://docs.streamlit.io/develop/api-reference/text/st.markdown 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. height : int or None Desired height of the UI element expressed in pixels. If this is ``None`` (default), the widget's initial height fits three lines. The height must be at least 68 pixels, which fits two lines. max_chars : int or None Maximum number of characters allowed in text area. 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. No two widgets may have the same key. help : str or None A tooltip that gets displayed next to the widget label. Streamlit only displays the tooltip when ``label_visibility="visible"``. If this is ``None`` (default), no tooltip is displayed. The tooltip can optionally contain GitHub-flavored Markdown, including the Markdown directives described in the ``body`` parameter of ``st.markdown``. on_change : callable An optional callback invoked when this text_area'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 area is empty. If None, no text is displayed. disabled : bool An optional boolean that disables the text area if set to ``True``. The default is ``False``. label_visibility : "visible", "hidden", or "collapsed" The visibility of the label. The default is ``"visible"``. If this is ``"hidden"``, Streamlit displays an empty spacer instead of the label, which can help keep the widget alligned with other widgets. If this is ``"collapsed"``, Streamlit displays no label or spacer. Returns ------- str or None The current value of the text area widget or ``None`` if no value has been provided by the user. Example ------- >>> import streamlit as st >>> >>> txt = st.text_area( ... "Text to analyze", ... "It was the best of times, it was the worst of times, it was the age of " ...
