How Do I Change the Background Colour of the Actual Dropdown Menu?

It is an ugly brown and I can't change it

Hi there,

You need to inject custom CSS code to your form to change dropdown menu option's background colors.

To do that, you need to add following CSS code:

select.form-dropdown > option {
    background-color: white !important;
}

Above, blue marked area represents the color of the dropdown menu option's background color, so you can adjust color by changing this value.

If you need extra help, please let us know.

Thanks.
