horizontal alignment of options in ipywidgets

问题

How to align items horizontally in multi-select menu?

Currently this gives me a vertical alignment of options:

widgets.SelectMultiple(options=['option-1','option-2', 'option-3', 'option-4', 'option-5'],
                            rows=5, layout=widgets.Layout(width='440px'))

I am looking for a way to align all the options in a single row.
