Drupal 11 compatibility

I reviewed this there are some issues related to Facets Module, as it is not converted to Drupal 11 yet.

Thanks
Samit K.

Applies cleanly and upgrade status under Drupal 10.3 goes green and test install on a Drupal 11 test installation was without flaws. Regarding the scope of this issue RTBC from here +1

Apply this MR for D11 now with:

    "repositories": {
        "https://packages.drupal.org/8": {
            "canonical": false,
            "type": "composer",

Hi @chr.fritsch,
I noticed branch and MR is raised against 8.x-1.x branch and I think this needs to be raised with 2.x branch

Hello,

I have created a patch for 8.x.1.15 to make it compatible with Drupal 11.
Since there is a scripting code info.yml file added by the packaging script from DO. So this patch will fail to apply, We can use orakili/composer-drupal-info-file-patch-helper package that prevents patch from failing as a workaround.

Tests are green again.

Changes looks good and great to see all jobs are green now ~~ marking this one RTBC.

Looks good too. We need a D11 release as soon as possible. Could the author of the module create a new release?

Thanks chr.fritsch. Looking forward to a D11-compatible release, for now getting by with the patch plus https://github.com/mglaman/composer-drupal-lenient

Hmm not sure what I'm doing wrong, I have both a select2 field on a content type and use the element in a custom field, with D10 it works but with 11.0.9, after applying the patch and rebuilding I am able to install the module and add fields etc but on both custom form and content type I get a broken field and console errors:

Uncaught TypeError: c.isArray is not a function

This happens with JS aggregation on or off.

I ran into the same issue and it stumped me as I'm not a front-end developer. Another developer on my team pointed out that Drupal 11 ships with jQuery 4, Select2 doesn't seem to support jQuery 4 yet, and the isArray method is deprecated in jQuery 4, hence the issue.

Here are some links that provide more context:

• https://github.com/select2/select2/issues/6298
• https://www.drupal.org/node/3445202
• https://api.jquery.com/jQuery.isArray/

So we decided to go with the Tagify module/library until this is resolved.

Hope that helps!

Oh silly me, that's what chr.fritsch was referring to - I needed to explicitly install the dev version of select2 from npm, which does have support for Jquery4. That's fine, although tagify looks very nice thanks for the tip, may try this at some point. Select2 JS is definitely showing its age.

This is how Webform seems to have fixed it:
