I have a dropdown widget with the options “1”, “2”, and “3”. I’d like to set up a js_on_event so that the glyph in my multi_line plot whose index matches the option clicked is selected – so if I choose, say “2”, the second line on my multi_line plot is selected (and thus highlighted). I tried to implement it like this, but the dropdown doesn’t appear to be doing anything at all.
Also, on a lesser note – is there any way to add a scroll bar to a dropdown for when there are more options than fit on the page?
