1. Uikit2 does not support bullet css class
You can use css code for uk-list-bullet
.uk-list-bullet>li{position:relative;padding-left:calc(1.5em + 10px)}
.uk-list-bullet>li::before{content:"";position:absolute;top:0;left:0;width:1.5em;height:1.5em;background-image:url("data:image/svg+xml;charset=UTF-8,%3Csvg%20width%3D%226%22%20height%3D%226%22%20viewBox%3D%220%200%206%206%22%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%3E%0A%20%20%20%20%3Ccircle%20fill%3D%22%23666%22%20cx%3D%223%22%20cy%3D%223%22%20r%3D%223%22%20%2F%3E%0A%3C%2Fsvg%3E");background-repeat:no-repeat;background-position:50% 50%;display:block}
2. Try this
a.dropdown-button:hover i {
color: red;
}
