A Tree layout allows users to view the embedded pages of a Page List as a tree. removed Page Group throughout per MARTT 1/12 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 7+, Firefox 3+ and Safari 4+ browsers; can display a custom skin; is localizable; and supports PRPC'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.
