Hi,
I’m not sure if you’re referring to the cell where the dropdown box is or the dropdown list.
If it is the former, you may consider modifying the style_data
or style_data_conditional
property.
Otherwise, I currently can only think of adding some CSS like this below.
.dash-table-container.Select-menu-outer {background:black;}
I’ll keep an eye out for a better way for you.
