Insert a new logical component; in the RFLP tree, right-click Logical, select Insert New Reference and then in the Logical dialog box click Finish.
The logical component appears in the RFLP tree under Logical and a 2D representation of the component is displayed. In this example the component is named Component #1.

Right-click the 2D representation of the new component you have just inserted, select Insert New Reference and then in the Logical dialog box click Finish.
A new logical component appears in the RFLP tree under the component created in step 1 and a 2D representation of the component is displayed inside the first component. In this example the new component is named Component #2.

Repeat step 2 two more times, each time inserting a new logical component inside Component #2.
The two new components (#3 and #4) cannot be displayed inside Component #2. Instead a symbol
indicates that additional components are present.

Click
to reveal the two additional components (if required, click
to hide them).
