+Boxes
+-----
+
+(:mod:`cubicweb.web.views.boxes`)
+
+*sidebox*
+  This view displays usually a side box of some related entities
+  in a primary view.
+
+The action box
+~~~~~~~~~~~~~~~
+
+The ``add_related`` is an automatic menu in the action box that allows to create
+an entity automatically related to the initial entity (context in
+which the box is displayed). By default, the links generated in this
+box are computed from the schema properties of the displayed entity,
+but it is possible to explicitly specify them thanks to the
+`cubicweb.web.views.uicfg.rmode` *relation tag*:
+
+* `link`, indicates that a relation is in general created pointing
+  to an existing entity and that we should not to display a link
+  for this relation
+
+* `create`, indicates that a relation is in general created pointing
+  to new entities and that we should display a link to create a new
+  entity and link to it automatically
+
+
+If necessary, it is possible to overwrite the method
+`relation_mode(rtype, targettype, x='subject')` to dynamically
+compute a relation creation category.
+
+Please note that if at least one action belongs to the `addrelated` category,
+the automatic behavior is desactivated in favor of an explicit behavior
+(e.g. display of `addrelated` category actions only).
