streamlit 下拉框的文本和选项框放在一行上显示
streamlit 下拉框的文本和选项框放在一行上显示，是否可以？如何设置 可以将下拉框的文本和选项框放在一行上显示，可以使用streamlit.beta_columns()函数将页面分成多列，然后将下拉框放在需要的列中。以下是示例代码：
import streamlit as st
# 使用 beta_columns 将页面分成两列
col1, col2 = st.beta_columns(2)
# 在第一列中添加文本
with col1:
st.write("下拉框：")
# 在第二列中添加下拉框
with col2:
option = st.selectbox("", ["选项1", "选项2", "选项3"])
# 隐藏下拉框的文本
st.markdown("<style>div.row-widget.stRadio > div{flex-direction:row;}</style>", unsafe_allow_html=True)
在上述代码中，我们将页面分成两列，将下拉框放在第二列中，并使用 CSS 隐藏了下拉框的文本。这样，下拉框的文本和选项框就可以在一行上显示了。 @isdkz 看看效果 def selectbox(

r"""Display a select widget.
Parameters
----------
label : str
A short label explaining to the user what this select widget 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, using the syntax ``:color``,
where ``color`` needs to be replaced with any of the following
supported colors: blue, green, orange, red, violet.
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 : Sequence, numpy.ndarray, pandas.Series, pandas.DataFrame, or pandas.Index
Labels for the select options. This will be cast to str internally
by default. For pandas.DataFrame, the first column is selected.
index : int
The index of the preselected option on first render.
format_func : function
Function to modify the display of the labels. 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 selectbox.
on_change : callable
An optional callback invoked when this selectbox'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 selectbox if set to True.
The default is False. This argument can only be supplied by keyword.
label_visibility : "visible" or "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". This argument can only be supplied by keyword.
还是得看源码啊，找到了用最后一个属性可以设置
