RadzenDropDown: customize the --rz-dropdown-item-selected-background-color

Hi, I am working on a RadzenDropDown multi-selection control. I need to change the default color of --rz-dropdown-item-selected-background-color in my .razor.css file. I have declared
--rz-dropdown-item-selected-background-color: var(--rz-secondary-dark); but still the default color from material-base.css is being loaded into the browser. Any help is appreciated here.

You can use the browser's devtools to inspect what is actually being applied.

Usually such style overrides should be added to the site.css file with a root level selector:

:root {
  --rz-dropdown-item-selected-background-color: var(--rz-secondary-dark);
}
