Hey guys, I want to check if a multi dropdown is empty or not
I tried to define the dropdown as such:
options = dd_options,
value = 
Then at app.callback I tried to check if the value is still an empty list in 3 different ways, using “if not”, “len() ==0” and " == ", none of them worked.
I also tried not defining the default value of “value” and saying “if is None”. Still didn’t work.
I also didn’t find anything to help me in the dropdown reference page.
