Much Selects can be styled with "external" CSS using the ::part
selector. It
works a lot like CSS classes, but it allows styles to "pierce"
the shadow DOM. The HTML in the shadow DOM has lots of ::part
attributes in it to allow you to style much-select's that way if you want to.
In this example we're adding some styles to the dropdown options. To make them a bit more interesting. We're adding some emiji's for the card suits, and changing the color of the text in the dropdown.
