I’m trying to limit the number of rows the user can select in a Datatable. However, it seems that auto-callbacks like this one are impossible (here, with a limit of 20):
@app.callback(Output('table', 'selected_row_indices'), [Input('table', 'selected_row_indices')]) def limit_row_indices(indices): if indices is not None: if len(indices>20): return indices[:20]
I understand that this prevents entering into an infinite loop. But is there a working solution to limit the number of rows selected by the user?
