I know that there are a bunch of widgets available in Bokeh, here:
https://docs.bokeh.org/en/latest/docs/user_guide/interaction/widgets.html
How can I integrate Bokeh Dropdown Menu with MultiSelect (or extend the Dropdown) in order to have a Multi-Select Dropdown? Is there anything built-in?
My expected result is a dropdown which one can select/deselect multiple options.
