Text not allowed in element “ul” in this context.

The <ul> element is used to define unordered lists, where each element must be contained within a <li> element, like in this example:

<ul>
  <li>first element</li>
  <li>second element</li>
  <li>third element</li>
</ul>

Ensure that there’s no content inside the <ul> element that is not contained within a <li> element.

Sometimes this error comes when trying to give a title to the list, for example:

<ul>
  Fruits
  <li>Apple</li>
  <li>Orange</li>
</ul>

Instead, that title text should be outside the list, like:

<span>Fruits</span>
<ul>
  <li>Apple</li>
  <li>Orange</li>
</ul>

Other times, this can come as the concatenation of <li> elements which results in something like:

<ul>
   <li>First item</li>
   &nbsp;
   <li>Second item</li>
  &nbsp;
   <li>Third item</li>
</ul>

Note how in this case that &nbsp; used to join the <li> is causing the problem, as it’s content that is not contained by a <li> element, as required by the <ul> element.
