Hiding the field in the "Manage Form display" does not work

Is this with the experimental "Field Layout" module? In that case be aware of #3370887: Inform users that Field Layout is deprecated.

Please add clear steps to reproduce in any case.

I can't reproduce this.

I did the following:

1. I installed a new Drupal site from the 11.x branch, which is at commit 501bbdbe21c257fc
2. I browsed to /admin/structure/types/manage/article/form-display.
3. I moved field Image to the Disabled section and saved the form.
4. Image remains in the disabled section.
5. I checked at /node/add/article that Image is in fact disabled.

Because of that, we need additional reproduction steps from you and perhaps error logging (including browser console errors, if any), to proceed here.

Thanks for that update. I repeated the steps in I outlined in comment #4, in Drupal 10.4.4, which as I write this is the latest release, and I could not reproduce the bug.

Can you confirm that there are no browser console errors or Drupal log errors whatsoever?

It would be possible to do something with that if you disable JavaScript aggregation, rebuild caches, then get that error with its stack trace for us.

Additionally, any information about what makes the affected Drupal site different from a newly-installed Drupal site will tend to help lead toward a resolution. Otherwise, we can only guess.

I have the same problem. Tried to hide fields for "Full content" display mode. After saving I get the message "Status message Your settings have been saved." but the fields are still listed in the "Content" section instead of the "Disabled" section. This used work until last week.

I use/run Drupal 11.1.5, once based/built on a Drupal CMS RC2 installation. Then always updated through Composer.

I use Display Suite (ds, 8.x-3.28) with the "1 col layout", have 2 field groups (field_group, 8.x-3.6) and Gin as a admin theme.

I tried it with switching/using a different admin theme (Claro, but the the saving still would not work) and switched Display Suite layouts (to 1-col with wrapper) but no difference here too.

This error shows up in my Firefox console. Tested it with Safari and Chrome too, same results there.

It still works for "Form display". There I can hide the fields but the same JS error pops up.

Hello,

Ran into the same issue, as a temporary workaround, you can click on "Show row weights" and use the dropdown to disable the field.

That worked for me at least.

Cheers

Experienced the same annoying bug. Drupal 10.5.2.

The workaround which worked was based on captain_canuck's hint. Show row weights by itself did not solve the issue. But once set to 0, I could hide weights and drag the unorderly field down.

"Great success!"

Thanks

Same bug on Drupal 11.2.

In my experience, it happened on a custom form mode, plus I have field_group module enabled.

Workaround in #15 still works on Drupal 11.2

I'm experiencing the same issue on Drupal 11.2.10 with field_group and gin installed.

Just to add to the datapoints, experiencing the problem with D10.6.3, field_group and claro. I think field_group is the likely culprit here.

Similar errors to #14: Uncaught TypeError: rowHandlers[data.rowHandler] is not a constructor
