Question

There is a tree style structure from which I want to keep only a specific branch.

The list is like:

ul.level-1
--li
----ul.level-2
------li
------li
--li
----ul.level-2
------li
------li
------li

By giving the element I’ve selected (a second level li element), I want to remove all top level li except the one this li belongs to.

Is this possible without iterating within the tree?

Answer 1

If I understand you correctly, this should do what you need:

$('li.selected').closest('li.toplevel').siblings('li').remove();
