Fieldset label (group-label)
Group related form fields with
<fieldset> and include a descriptive
<legend> for each group.
Missing fieldset:
In this example there is missing
<fieldset>.
The (DOM/programmatic) structure of the above example looks like this:
</legend>
Choose your favorite fruits:<legend>
<input type="checkbox" name="fruit" value="apple" />
Apple
<input type="checkbox" name="fruit" value="banana" />
Banana
Note: Hard to automatically test or detect. Requires a human tester or AI
to determine if a <fieldset> element is
needed and where (i.e. which form elements are related), and ensure that a
<fieldset>
exists if necessary.
