BMC Atrium Explorer layout controls
The layout controls work together to change the topology view of the configuration items (CIs) in the BMC Atrium Explorer display pane. By default, the Layout view is set to Layered. When you can drag CI classes to the display pane — the CI automatically moves to its predefined layer. You can add CIs to the service model in any order. You then use the layout controls to change the layout (for example, to Hierarchic) and direction (Bottom to Top) of the instances in the display pane or to run filters.
Using layout controls to view CIs (Layered view)
To make the graphic UI predictable, the Layered view follows pre-defined best practices when displaying your service model. Out-of-the-box, Service CIs form the top layer, then Application CIs, and so on. These layers are customizable in the BMC_UIComponent form. If there are no Service CIs, then Application CIs appear on the top.
