Help with displaying two graphs in 1 row, 2 columns

thanks all for the great tips and tricks!

for the time being I chose the solution from @giodcruz95 (easiest to implement)

I’m also investigating the nice approach suggested by @tcbegley. However with the changes suggested by the author:

        dbc.Row([
            #Boxplot
            dbc.Col([
                dcc.Markdown('Select grouping variable'),
                dcc.Dropdown(
                    id='group_var',
                    options=[{'label':i, 'value':i} for i in feats_cat],
                    value='GB'),
                dcc.Graph(id='var_boxplot')
                    ]), 
            
            dbc.Col([
                #Step change cuts 
                dcc.Graph(id='var_stepchanges')
                    ]),
                ]),

unfortunately I get the two plots now in two rows (i.e. below each other).
And where exactly can I find the assets folder?
Thanks a lot!
