+elements are yet present.

+ <li><b> Mesh, sub-mesh, group </b> This button allows you selecting either

+ <li><b> Set Filter </b> button allows you selecting elements or nodes
+by filtering elements or nodes of the mesh with different criteria
+(see \ref filtering_elements "Filter usage" on how to set up selection
