Using tootips with lists [HTML, CSS]

Question

Looked at W3School's tooltips guide and basically retyped it, but the example doesn't use a list, and I am using a list for a practice website I'm doing. As a result, it's formatted weirdly.

I tried messing around with it, removing the li tag and it worked but it isn't what I'm looking for.

h1 {
    color: #D3D3D3;
}

.tooltip {
    position: relative;
    display: inline-block;
    border-bottom: 1px dotted black;
}

.tooltip .tooltiptext {
    visibility: hidden;
    width: 120px;
    background-color: #555;
    color: #fff;
    text-align: center;
    border-radius: 6px;
    padding: 5px 0;
    position: absolute;
    z-index: 1;
    bottom: 125%;
    left: 50%;
    margin-left: -60px;
    opacity: 0;
    transition: opacity 0.3s;
}

.tooltip .toolptiptext::after; {
    content: "";
    position: absolute;
    top: 100%;
    left: 50%;
    margin-left: -5px;
    border-width: 5px;
    border-style: solid;
    border-color: #555 transparent transparent transparent;
}

.tooltip:hover .tooltiptext {
    visibility: visible;
    opacity: 1;
    }

I expect it to be a list that when you hover over it'll show the tooltip, formatted the same as a regular HTML list. That's really it.

.tooltiplink::after {
  visibility: hidden;
  content: attr(name);
  background-color: #555;
  color: #fff;
  text-align: center;
  border-radius: 6px;
  padding: 5px 0;
  position: absolute;
  margin: -1rem;
  padding: 5px;
  border-style: solid;
  border-color: #555 transparent transparent transparent;
  opacity: 0;
  transition: opacity 0.3s;
}
.tooltiplink:hover::after {
  visibility: visible;
  opacity: 1;
}

<ul>
  <li class="tooltiplink" name="This is a tooltip">Option 1
  </li>
  <li class="tooltiplink" name="This is a tooltip for the 2th option">Option 2
  </li>
  <li class="tooltiplink" name="This is a tooltip for the 3th option">Option 3
  </li>
</ul>
