What happened:

Problem description:

Incorrect use of \

The label's for attribute doesn't match any element id. This might prevent the browser from correctly autofilling the form and accessibility tools from working correctly.

To fix this issue, make sure the label's for attribute references the correct id of a form field.

Suggested solution:

Not sure if this is a false positive as the component still seems to work as intended.

Hi. Which examples, exactly? The ones I checked work.

Hi @silviuaavram,

Yes, the components work as expected but we still get the following error in the DevTools issues panel.

7 resources affected, so I'm guessing it affects all the examples on the page:

[silviuaavram]

Well, devTools may be wrong. Specifically here, there are no issues, the ids match, the click and focus technique works, not sure what we can do about it.

[silviuaavram]

Maybe, just maybe, it complains that the target is a div, not a form element.

Now, to be honest, I don't think we need the for here in the label markup. If I remember we manually focus the div on label click, and we also use aria labelledby on the div in order to get the markup from the label.

If I'm correct I propose to fix it by removing the for attribute, update the unit tests, and check that the click/focus and label works as before. Let me know if you want to create a PR. Thank you!

Switching to a button element removes the DevTools error but it also changes the behaviour of the component (clicking on the label will now open the menu, instead of just focusing on the element like before).

According to the Wayback Machine it looks like Downshift used to recommend using a button element but switched to a div element a few years ago to be WAI-ARIA 1.2 compliant https://github.com/downshift-js/downshift/issues/1335

Removing the htmlFor attribute from the label element causes another issue:

A <label> isn't associated with a form field.

Hard to know what to do, we’re probably going to stick with the div element and treat it as a false positive.

That’s true, we performed this change a few versions ago. Consequently I would try the implementation without the for attribute and double check if it’s working properly from the a11y point of view.

I updated my previous comment shortly after posing it as I forgot to mention what happens when you remove the htmlFor attribute from the label element.

Closing since we can't do any relevant fix here, and the end result is actually what we want.
