scroll down button for widgets?

I have a large list for a user to select from a widget (i.e. “Select” widget). The user needs to scroll down the list to see it in its entirety and make a selection. The scroll down bar only appears when scrolling is in progress. Is there a way to always keep the scroll down bar visible as soon as bokeh is loaded?

Unless the user is aware they can scroll down, there is no other way of informing the user there are more selection options.

Hi,

AFAIK there is not. You might try to examine the generated HTML output to see what CSS classes the Bokeh select widget has (I don't know them offhand) and then target these with custom CSS rules to change the behavior of the scrollbar. Alternatively, Bokeh is extensible. You could wrap any selection widget however you like and include in your document instead of the standard Bokeh select:
