Interactivity between different inputs elements in Bokeh

Hi,

I have the following test data =

{

“prd” : [“a”, “b”, “c”]

“code” : [“1”, “2”, “3”]

}

I have 2 dropdown select elements in my bokeh app. For simplicity sake, let’s call them d1 and d2. d1 shows the all the keys in the above dictionary (prd, code) and d2 should be dynamically reflect what gets selected in d1. For eg. If I select “code” in d1, then d2 dropdown should give me options as (1,2,3)

Is this possible in bokeh? I couldn’t find an example in the repo. Any code examples would be appreciated.

Thank you in advance.

Regards,

V

Try using a callback function. something like that should work

def change_d2(attr,old, new):

d2.options=data[d1.value]

d1.on_change(‘value’,change_d2)

Thank you, George! That really helped

I was missing d2.options=data[d1.value]. I was assigning data[d1.value] to a variable rather than d2.options.
