Use this tool set to display or hide the graphics for supported entities in the browser list.  

The Elements/Geometry/Both button determines what the other buttons act on; left-click the small triangular downward arrow to reveal a drop-down menu of options. You can select Elements, Geometry, or Both.

Use the Display All, Display None, and Display Reverse buttons at the top of the tab to change the display state of all assemblies, multibodies, components, groups, system cols, load cols, and vector cols shown in the list. All displays and None hides all of the items shown in the list/tree. Display Reverse, reverses the state of all the entities (displaying the hidden, and hiding the displayed). If you have multiple link entities selected in the browser list, then HyperMesh will only perform these actions on the selected entities. To deselect all currently selected entities, left-click in any empty "white space" within the browser list, such as between columns. To clear the selected entities in the browser, make sure the browser is active, and then press ESC.
