A short label explaining to the user what this button 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.

The url to be opened on user click

An optional tooltip that gets displayed when the button is hovered over.

An optional string that specifies the button type. Can be "primary" for a button with additional emphasis or "secondary" for a normal button. Defaults to "secondary".

An optional emoji or icon to display next to the button label. If icon is None (default), no icon is displayed. If icon is a string, the following options are valid:

• A single-character emoji. For example, you can set icon="🚨" or icon="🔥". Emoji short codes are not supported.

• An icon from the Material Symbols library (rounded style) in the format ":material/icon_name:" where "icon_name" is the name of the icon in snake case.

  For example, icon=":material/thumb_up:" will display the Thumb Up icon. Find additional icons in the Material Symbols font library.

An optional boolean that disables the link button if set to True. The default is False.

Whether to expand the button's width to fill its parent container. If use_container_width is False (default), Streamlit sizes the button to fit its contents. If use_container_width is True, the width of the button matches its parent container.

In both cases, if the contents of the button are wider than the parent container, the contents will line wrap.
