Not able to change background colors on dropdowns

Hi there.

I'm changing background colors for dropdowns, and it changes in apple computers, but it doesn't change in the actual form on windows computers. It's not browser specific, but it looks like windows is keeping dropdown to black and blue which is hard for our customers to see. Please help.

You can use the CSS editor using the Form Designer to change the background color of the Dropdown option.

Example: 

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

in the exampl, it becomes like this

Hope this help. Let us know how it goes for you.

Thanks.
