You cannot delete a list entry permanently from the system. You can hide it (make
it inaccessible) using the List entries : <name of the list>
page. To hide a list entry, it needs to go through at least one round of the approval
process.
On the List entries : <name of the list> page, select
the entry that you want to hide, and click the Delete List
Entry icon. To hide multiple entries, select all of those.
Enter the reason of deletion in the Comments text box of
the Delete List Entry pop-up.
