[BUG] AttributeError("Dropdown' object has no attribute 'multi")

[whz11]

I was able to use multi parameter in Dash version 2.7.0, but it does not pass the online test on edstem. I would like to know in which version of Dash the dropdown component does not have the multi parameter and what alternative is used.

 dcc.Dropdown(
        id="region",
        options=regions,
        value=[],
        multi=True,
        clearable=False
    ),

What do you mean by does not pass the online test on edstem. ?

The Dropdown always had the multi argument to allow multiple choices to be selected.
