Plotly histogram drop down button

Trying to create a histogram with a drop down button so you can switch between views. Want the drop down button to be a list of the column names. The following code gives a histogram with a button but the button only has one option which is the final column. How do I get it so the button is a drop down list of all the column names?

d = {'col1': [1, 2], 'col2': [3, 4]} df_date_all = pd.DataFrame(data=d)

fig_drop = go.FigureWidget() addAll = True

for column in df_date_all.columns.to_list():

try:
    fig_drop.add_trace(
    go.Histogram(
        x = df_date_all[column],
        name = column
    )
    )
    fig_drop.update_layout(
        updatemenus=[go.layout.Updatemenu(
            active = 0,
            buttons = list([
                dict(label = column,
                method = 'update',
                args = [{'visible': df_date_all.columns.isin([column]),
                            'title': column,
                            'showlegend': False}])
            ])
        )
    ])

    fig_drop.update_layout(
    title_text='Frequency by Date', 
    xaxis_title_text='Date', 
    yaxis_title_text='Query Count')
except:
    pass

fig_drop.show()
