Creating a Group Particle from the Toolbox

You can create a group particle with the Group Particle tool in the Toolbox.

Select a group particle tool (Sequence, Choice, or All) in the Toolbox, and then click the element symbol in the diagram.

A group particle is created and its symbol is displayed in the diagram, linked to the element symbol.
Select the Element tool in the Toolbox and then click the group particle symbol to add an element item. Click the symbol again to add additional elements.

The child elements appear one by one in the diagram, linked to the group particle symbol.
Right-click in order to recover the Pointer.

Note: When you click an element symbol with the Element tool, a sequence symbol (by default) is displayed in the diagram between the parent element and the child element. To add other child elements, click the sequence symbol with the Element tool. To change the group particle, double-click the sequence symbol to display its property sheet, then select another group particle in the Type list and click OK.
