How do we specify the background color for the drop downs? I hate the white background and want to make it more stylish and transparent.
You will need to use classes for that to subclass the main styling, as they are part of the bootstrap framework, Blocs doesn’t support styling the dropdown menu backgrounds directly.
You may be able to get AI to generate you the CSS (custom bootstrap dropdown menu background colours) for this and just paste it into the additional style zone in the Code Editor.
A more minor customisation option in Blocs is the Bootstrap 5 theme option, which will turn the dropdown background dark.
I hope that helps.
