python-3.x - 调整 Bokeh 下拉菜单和其他小部件的大小

Question

如何在 Python 中使用 Bokeh 调整下拉列表或其他小部件的大小？

我有以下下拉列表作为图形的过滤器:



如您所见，它们的长度各不相同。它们在这样的小部件框中:

widgets = widgetbox([school_selector,
                degree_selector,
                student_selector,
                began_exam_selector,
                finished_exam_selector],
                sizing_mode='fixed')

它会被放入最终的布局中，如下所示:

dashboard_layout = column(widgets, column(time_v_note, exam_data_table))
curdoc().add_root(dashboard_layout)

我试过 'fixed' , 'scale_width' , 和 'stretch_both'作为 sizing_mode 的选项但什么都没有改变。我只希望所有过滤器的尺寸相同，这样就没有锯齿状边缘。

谢谢

Select() 结构如下所示:

#### School Selector
## Selection Options
school_select_opts = ['All'] + list(exam_df['School ID - School Name'].unique())

## Selector Build
school_selector = Select(title='1) Choose a School:',
                         options=school_select_opts,
                         value='All')

#### Degree Selector
## Selection Options
degree_select_opts = ['All'] + list(exam_df['Degree'].unique())

## Selector Build
degree_selector = Select(title='2) Choose a Degree:',
                         options=degree_select_opts,
                         value='All')

#### Exam Selector
## Selection Options
exam_select_opts = ['All'] + list(exam_df['Exam ID - Exam Name'].unique())

## Selector Build
exam_selector = Select(title='3) Choose an Exam:',
                       options=exam_select_opts,
                       value='All')

                         value='All')

                                value='All')

只需记下宽度并提及它的值(value)，您就会得到所需的答案。

代码 :

menu = [("Delhi", "3"), ("Mumbai", "4"), ("Chennai", "4"), ("Kochi", "6"), ("Kolkata", "7")]

dropdown = Dropdown(label="LOCATION", button_type="success", menu=menu,width=120)
