+In Mesh module it is possible to create groups of mesh elements:
+nodes, edges, faces or volumes. One group contains elements of only
+one type. The following ways of creation are possible:
+
+- by selecting the elements using filters and/or directly on the
+ presentation in the VTK viewer, and/or by using elements of other
+ mesh objects - \ref standalone_group "Standalone group"
+ tab of \ref creating_groups_page "Create group" dialog.
+- by creating a group of elements generated on the chosen geometrical
+ object - \ref group_on_geom "Group on geometry" tab of
+ \subpage creating_groups_page "Create group" dialog and
+ \subpage create_groups_from_geometry_page "Create Groups from Geometry"
+ dialog.
+- by creating a group of elements satisfying to certain criteria -
+ \ref group_on_filter "Group on filter" tab of
+ \subpage creating_groups_page "Create group" dialog.
+- by creating groups of nodes and elements from the chosen submesh
+ (type of elements depends on dimension of submesh geometry) -
+ using <b>Mesh -> Construct Group</b> menu item (available in context
+ menu as well).
+- by creating groups of entities from existing groups of superior
+ dimensions - using \subpage group_of_underlying_elements_page
+ "Create Group of Underlying Elements" dialog.
+
+The created groups can be later:
+
+- \subpage editing_groups_page "Edited"
+- \subpage using_operations_on_groups_page "Subjected to Boolean operations"
+- \subpage deleting_groups_page "Deleted"
+
+An important tool, providing filters for creation of \b Standalone
+groups is \ref selection_filter_library_page.
