To maintain the bullets you can replace the list-style: none with list-style-position: inside or the shorthand list-style: inside:

ul {
  list-style-position: inside;
  padding-left: 0;
}

ul {
  list-style-position: inside;
  padding-left: 0;
}

<ul>
    <li>Milk</li>
    <li>Cheese
        <ul>
            <li>Blue cheese</li>
            <li>Feta</li>
        </ul>
    </li>
</ul>
