Problem/Motivation

When dragging a group of table rows (e.g. in a hierarchical menu), the classes for "tree-child", "tree-child-first", and "tree-child-horizontal" are not added. This makes it so that the visual representation of the tree being dragged is not shown. The last class, "tree-child-last" actually continues to work.

Here's a screenshot *while dragging* an item. You can see the lack of tree indicators except for the last item (Views).

Proposed resolution

Fix the addition of classes in Drupal.tableDrag.prototype.row.prototype.findChildren().

Remaining tasks

Review and test.

User interface changes

None, other than fixing the functionality

API changes

None.

Patch attached. I also changed the variable "currentRow" to be "$currentRow", since it's a jQuery object. Since this is a variable scoped inside of .findChildren() it shouldn't have any other effect and just makes that function follow our variable naming pattern.

Attached before and after photos as well.

Any chance you can change the rowIndentation signature so that it follows jQuery's wrong order for each() params instead of having to use this? rowIndentation(indentNum, el)

@quicksketch, Thank you for reporting this problem and making a patch.. We rely on issue reports like this to improve Drupal core.

I tested this on 9.5.x, standard install, and was not able to reproduce this error.

Therefore, closing as outdated. If this is incorrect reopen the issue, by setting the status to 'Active', and add a comment explaining what still needs to be done.

Thanks!
