+    This option allows to define one of the available level options
+    as the default level to use.
+
+    When searching for records in the :guilabel:`Web > List` module as well as
+    the database browser, it is possible to select the search levels (page tree
+    levels to respect in the search).
+
+    An editor is therefore able to select between the current page, a couple of
+    defined levels (e.g. 1, 2, 3) as well as the special "infinite levels".
+
+    Those options can already be extended using the TSconfig option
+    :confval:`mod-web-list-searchLevel-items`.
