(v 3.3) mobile menu stopped working properly.

Additional information:
a)
D9.5.11
php 8.2
Droopler 3.2.0-rc1
Drupal Mega Menu 8.x-1.16 (or Drupal Mega Menu 8.x-1.14) + patch
This menu setup works fine

After update:
b)
D10.1.4
php 8.2
Droopler 3.3.0-rc1
Drupal Mega Menu 8.x-1.16 (or Drupal Mega Menu 8.x-1.14) + patch
Unfortunately, it either doesn't work at all or develops and disappears.

same issue here (droopler 3.2.0)

Same here.

This seems to be related to " Remove jQuery dependency from the once feature → ".

A patch would be great.

in my local I've fixed the issue by recompiling theme (in web/profiles & web/themes/custom). But the issue stills occurs after deployment.

In my droopler custom theme, I saw some calls from web/profiles/contrib/droopler/custom/themes/droopler_theme/js files.
The .gitignore contains !/web/profiles/custom but there is nothing there.

As a quick workaround I've added a line !/web/profiles/contrib/droopler to include the web/profiles/contrib/droopler files in git then deploy is ok

Hope it helps

I have created a pull request with a fix.

In the meantime, you can use the commit as a patch with composer by adding the following line to the patches section of your composer.json.

            "droptica/droopler": {
                "Remove JQuery.Once": "https://git.drupalcode.org/project/droopler/-/merge_requests/5.diff"
            }

Then apply the patch:

composer update droptica/droopler

After this, it may be useful to recompile your base theme:

cd web/profiles/contrib/droopler/themes/custom/droopler_theme
npm install -g npm
npm install gulp
gulp compile
drush cr

Note that every time you patch a module or a theme, the entire content is rewritten by composer. Therefore, after patching, you have to recompile the base theme.

Depending on how your CSS is committed into the repository, it may be possible that the new JS and CSS code generated during the compilation will not be added to the repository. It is up to you how you bring the new JS and CSS code generated inside the base theme into your repository and, ultimately, into your live website. If you don't bring this code to your live website, you'll see the menu working locally while broken on production.
