Deletion of single element in leaf-list

Hi,
Thanks for your reply.

For question mentioned in, Configured values not appearing in possible completions for "no" command of a leaf-list node, the justified answer is that “no” will remove the leaf-list completely.
It is possible to remove individual elements in leaf-list, then why values do not appear in possible completions for “no” command of a leaf-list.
This is wrt Confd 6.4.3
Also what is recommended way to delete leaf-list?
