This also allows you to render a range slider by passing a two-element
tuple or list as the value.
The difference between st.select_slider and st.slider is that
select_slider accepts any datatype and takes an iterable set of
options, while st.slider only accepts numerical or date/time data and
takes a range as input.
Function signature[source] st.select_slider(label, options=(), value=None, format_func=special_internal_function, key=None, help=None, on_change=None, args=None, kwargs=None, *, disabled=False, label_visibility="visible") Parameters

label
(str)

 
A short label explaining to the user what this slider 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.


options
(Iterable)

 
Labels for the select options in an Iterable. For example, this can
be a list, numpy.ndarray, pandas.Series, pandas.DataFrame, or
pandas.Index. For pandas.DataFrame, the first column is used.
Each label will be cast to str internally by default.


value
(a supported type or a tuple/list of supported types or None)

 
The value of the slider when it first renders. If a tuple/list
of two values is passed here, then a range slider with those lower
and upper bounds is rendered. For example, if set to (1, 10) the
slider will have a selectable range between 1 and 10.
Defaults to first option.


format_func
(function)

 
Function to modify the display of the labels from the options.
argument. It receives the option as an argument and its output
will be cast to str.


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.


help
(str)

 
An optional tooltip that gets displayed next to the select slider.


on_change
(callable)

 
An optional callback invoked when this select_slider'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.


disabled
(bool)

 
An optional boolean, which disables the select slider 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".
Returns(any value or tuple of any value)  The current value of the slider widget. The return type will match
the data type of the value parameter.
Examples
import streamlit as st

color = st.select_slider(
    "Select a color of the rainbow",
    options=["red", "orange", "yellow", "green", "blue", "indigo", "violet"])
st.write("My favorite color is", color)

And here's an example of a range select slider:

import streamlit as st

start_color, end_color = st.select_slider(
    "Select a range of color wavelength",
    options=["red", "orange", "yellow", "green", "blue", "indigo", "violet"],
    value=("red", "blue"))
st.write("You selected wavelengths between", start_color, "and", end_color)
