| Developing and Deploying Siebel Business Applications > Pick Lists, Drilldowns, and MVGs >  Configuring Multi-Value Groups
 Multi-value groups (MVGs) incorporate child data into an applet. They provide you with a way to display multiple child records for a single parent record, yet they do not require a master-detail view. Instead, the user clicks the select button in a multi-value field, and an MVG applet pops up displaying a set of child records. For example, NREC's requirement is to create a MVG on the Opportunity Form Applet (SCW) to display the contacts associated with each opportunity. The results of the configuration work are shown in Figure 25.
