Usage instructions

Parameters

• label (str, default None): The label for the slider component.
• min_value (float, default 0): The minimum value of the slider.
• max_value (float, default 100): The maximum value of the slider.
• value (float, default 50): The initial value of the slider.
• step (float, default 1): The step size for each slider movement.
• format (str, default None): A printf-style format string controlling how the interface should display numbers. This follows the d3-format specification. Check d3-format.
• options (dict, default None): Additional options for the slider component. Options include:
  • color (str, default primary theme color): This sets the color of the slider.
  • marks (bool, default False): Set initial and final marks.
  • disableUnderline (bool, default False): If True, the underline of the input box is disabled.
  • labelPosition (str, default "top"): The position of the label. Can be "top" or "left".
  • labelTextAlign (str, default "left"): The text alignment of the label. Can be "left", "center", "right", "justify", or "inherit".
  • fontSize (float, default 12): The font size.
  • endAdornment (str, default None): The text at the end of the input box.
  • labelWidth (str, default "20%"): The width of the label.
  • sliderWidth (str, default "60%"): The width of the slider.
  • inputWidth (str, default "20%"): The width of the input box.
• key (str or None, default None): An optional key that uniquely identifies this component. If this is None, and the component's arguments are changed, the component will be re-mounted in the Streamlit frontend and lose its current state.
• on_change (Callable, default None): A callback function that is called whenever the slider value changes.
• args (tuple, default None): Additional arguments to pass to the callback function.
• kwargs (dict, default None): Additional keyword arguments to pass to the callback function.

Function Returns

• float: The current value of the slider. This is the value passed to Streamlit.setComponentValue on the frontend.
