Checkbox and radio buttons

If no error messages on Drupal or JavaScript, I suggest to check if custom buttons are enabled.

I mean "form widgets":
/admin/appearance/settings/SUBTHEMENAME
Components -> Form

I just ran into the same problem that checkboxes and radio buttons can no longer be selected by clicking on their label. After some investigation I found out that the reason is that the label element is missing the "for" attribute. This must have to do with templates/form/form-element.html.twig file and I'm looking further, how to fix that.

OK, the problem is that

<label {{ label_attributes.addClass(labelclass).setAttribute('for', input_attributes.id) }}>

does not output any attributes. I don't know why that is but as a quick fix and workaround I have changed that code to

<label for="{{ input_attributes.id }}">

which at least outputs the "for" attribute and brings back proper functionality.

I have this issue after update bootstrap barrio

Config like this make my layout builder's checkbox can work

For some reason variable "input_attributes.id" is not set in "bootstrap_barrio_preprocess_form_element" and setAttribute('for', input_attributes.id) doesn't return empty attribute.

Here is the commit where condition added :- Git commit [Issue #2892364]

Patch to return empty "for" attribute if input_attributes.id not set in preprocessor.

/admin/appearance/settings/SUBTHEMENAME
Components -> Form

Custom type does not work.
Patch above can fix the clickable area for Standard type label, but Custom type has still invisible checkboxes (only labels are visible).
It looks like the real checkboxes are hiding with css, but Bootstrap4 custom pseudo-checkboxes do not appear on the page.

5.0.0-beta2

I can't relate to the original issue, but I came here because of #3137559, after which checkbox labels has no parameters at all.

Can confirm #11 fixing the issue I'm having. My exact issue was that behat test couldn't find checkbox from the site (also using webform) since label was missing "for" attribute.

I confirm that this is related to #3137559
The issue is that checkbox labels are using label_attributes which is not initialized.
Patch added to initialize it and to use an optional #label_attributes key element.

I have the same problem, after updating to 4.30, the attributes for the labels are gone, and patch in #14 is working for me with Drupal 8.9.1.

Thanks a lot!

After checking the other issue #3137559 , I am thinking that probably a better fix for this issue will be just initialising the label_attributes in the template itself, as it's done in the other ticket:

+{%
+  set label_attributes = create_attribute()
+%}

Any comments on this?

#12 + #16
Adding {% set label_attributes = create_attribute() %} to the form-element.html.twig Template (in a subtheme) fixed custom checkboxes!

Many thanks!

Patch in #14 works.

I am submitting a patch following my comment in #16.

What i am doing is checking if the label_attributes variable is initialised in the template file. This has two benefits:

* The value of the variable can still be preprocessed, but there is no initial need for it.
* If the preprocessing somehow removes or set to null that variable, the template will still works.

I have tested it in my site and seems to work fine with 8.9.1
Thanks
