Dashtable Dropdown typeerror

Hi, I am running the Dash dropdown example from the user guide but always returns the type error below. I have tried to update dash but it still didn’t work.

TypeError: Unexpected keyword argument dropdown
Allowed arguments: active_cell, column_conditional_dropdowns, column_conditional_tooltips, column_static_dropdown, column_static_tooltip, columns, content_style, css, data, data_previous, data_timestamp, derived_filter_structure, derived_viewport_data, derived_viewport_indices, derived_viewport_row_ids, derived_viewport_selected_row_ids, derived_viewport_selected_rows, derived_virtual_data, derived_virtual_indices, derived_virtual_row_ids, derived_virtual_selected_row_ids, derived_virtual_selected_rows, dropdown_properties, editable, end_cell, filter, filtering, filtering_type, filtering_types, id, is_focused, locale_format, merge_duplicate_headers, n_fixed_columns, n_fixed_rows, navigation, pagination_mode, pagination_settings, row_deletable, row_selectable, selected_cells, selected_row_ids, selected_rows, sort_by, sorting, sorting_treat_empty_string_as_none, sorting_type, start_cell, style_as_list_view, style_cell, style_cell_conditional, style_data, style_data_conditional, style_filter, style_filter_conditional, style_header, style_header_conditional, style_table, tooltip_delay, tooltip_duration, tooltips, virtualization

I believe that you’ll need to upgrade Dash - the syntax on the user guide is using the latest version: pip install dash —upgrade

Hey Chriddyp, thank you for answer my question. I have already upgraded the dash and dashtable but the problem is still there. The dashtable is currently in version 4.0.1. Thank you again for your help!
