input boxes of widgets inline (e.g. DatetimeRangeInput-widget)

[kmanitor]

Is your feature request related to a problem? Please describe.

It's not really a problem, but I have sidebar containing a DatetimeRangeInput-widget. This widget has two input boxes (in my case dates only) which are positioned below each other. Some widgets have a "inline=True" keyword (e.g. RadioBoxGroup-widget), but this widget doesn't, which was confirmed when I asked the question on discourse.holoviz.org.

Describe the solution you'd like

I would like to have the option to position the input boxes of the widget DatetimeRangeInput inline (but below the widget label)

Describe alternatives you've considered

It's possible to use CSS to position all widget components (label + input boxes) inline, but in most cases that would be too many things inline when considering a sidebar.
