Overview of Using View Templates
Each shaded area in the view diagrams in View Templates represents an area where you can place one or more applets. Siebel CRM expands each applet horizontally to fit the column where you place this applet. The amount of data that it displays determines the amount of vertical space the applet uses.
Siebel Tools does not determine style. It might display color schemes and applet titles differently than Siebel CRM displays them in the client.
