A Tree layout allows users to view the embedded pages of a Page List, or the entries in a Value List property, as a tree. The user can click branches to display or hide their leaves. The tree can display embedded relationships as deep as twenty levels. The developer specifies which page property to display as the name of each branch; each branch corresponds to a single embedded page or property.

The tree displays correctly in Internet Explorer 6+, Firefox 3+ and Safari 2+ browsers; can display a custom skin; is localizable; and supports Process Commander's accessibility features.

The tree is created dynamically, and will have as many branches as needed to display the requested data.

The tree may be read-only, simply displaying the hierarchy of property values. The developer may specify that the user can access the properties for each branch by clicking.

Depending on parameters, users may be able to add or delete rows, to reorder rows, and to apply actions to rows by clicking action buttons. The action buttons may appear in areas above or below the data. Express action buttons can appear in each row, or only in the row that the user has clicked.

Use either of two ways to add a Tree Layout to a section:

1. From the Explorer panel, drag the page list or value list that will be displayed onto a section. When you release the mouse button, a screen appears asking you to specify which repeating layout to use. Select Tree.
2. Select the Layout control from the Layout tab and drag it onto the section. In the screen that appears, select the Repeating radio button and Tree for the type of repeating layout.
