Support for widgets, similar to `animation_frame`?

[indiana-nikel]

Is there a simple way to add widgets (dropdown menus, checkboxes, radio buttons, etc.) similar to the way animation_frame is implemented? The reason for this ask rather than using ipywidgets is that the animation_frame's resulting widget remains functional when rendered to HTML. Unfortunately, ipywidgets doesn't have this capability (that I'm aware of).

I tend to distribute notebooks in HTML format for non-technical stakeholders who may not have Python (and jupyter, and...) installed. Having the ability to utilize widgets in plotting would solve a lot of the "I guess we'll have a plot for every city" discussions and notebook bloating.
