The 2026 Drupal Business Survey is open. Your response will help shape the future of the Drupal business ecosystem.When you want to print multi-level lists with item_list theme, there is a configuration where the $data variable is not reset. This create duplicates in the rendered list.
Example:
$items = array(
array(
'children' => array('item 1', 'item 2'),
),
array(
'children' => array('item 3', 'item 4'),
),
);
theme('item_list', $items);The result is:
-
- item 1
- item 2
-
- item 1
- item 2
- item 3
- item 4

Comment #13
lars toomre commentedNeeds to be fixed in D8 first before D7 and D6 patches will even be considered.
This simple one line initializing the $data value looks good to me, but I do not have a testing environment to test the patch.
Comment #14
lars toomre commentedUpdating the issue tags so flagged for backporting to D7 and D6.
Comment #15

sunSorry, but we need tests here.
Though this patch also somewhat duplicates the work in #256827: Various bugs in theme_item_list()
Comment #18
tim.plunkettThis was apparently committed already in D7 and obsolete in D8.
