Note: The Row Repeat layout is deprecated. As a best practice, convert existing Row Repeat layouts to Grid layouts. See Adding a Grid layout.
The Row Repeat layout presents each item from the source in horizontal rows, typically with labels in the top row. The items can be one of the following sources:
Page List or Page Group propertyTo see an example, review the standard section named Work-.PartyDetail, which is based on the Page Group property Work-.pyWorkParty. Special processing in this rule supports restrictions that specify which parties must be present and which parties can appear more than once.
Configure styles for Row Repeat layouts using the Skin rule. See Skin form — Components tab — Layouts — Repeat row/columns.
Six repeating layouts are available: Row Repeat, Column Repeat, Tabbed Repeat, Grid, Tree Grid, and Tree. They provide similar options but differing presentations; choose the one appropriate to your application and user interface needs. Configure styles for repeating layouts using the Skin rule.
To specify a data page as the source, select Property for the Source in the Row Repeat properties panel, and then enter the data page rule and property name in the List/Group field (for example, D_Products.pxResults). Alternatively, you can enter the name of the data page rule in the Pages & Classes tab, and then use the SmartPrompt in the List/Group field to select the named page. At runtime, if the data page does not already exist on the clipboard, the system creates it on the first reference.
Click the down-arrow 
at the right end of the Layout control group 
and select the Layout control 
. Click and drag the control. When the pointer changes shape to indicate that you can drop the layout, release the mouse button. A pop-up window opens to select the layout type:
Row as the repeat type.To delete a Row Repeat layout, select the layout and click the Delete Row button (
). Do not use the Delete Cell button for this action.
The table initially contains three columns and three rows. Usually, the top row holds labels, the second row holds fields (property values), and the final row contains the Add Row control (
). When the section appears at runtime, the second row is repeated for each element from the data source (for example, for each page in the Page List or Page Group property or each row from the report definition).
Click (
) to open the Row Repeat panel. Complete all tabs of the panel.
Your updates to this panel update the rule form upon clicking Apply. If the panel is pinned (
), the wireframe presentation on the rule form changes immediately to reflect your inputs. If the panel is not pinned (
), click Apply to apply your inputs.

| Append Activity | This field is visible only when Allow Update is selected on the General tab. Leave blank in most cases. To override the default behavior when a user adds a row to the array, identify the second key part of an activity to be called. Design your activity to accept the same parameters as the default activity Work-.AppendToPageGroup or Work-.AppendToPageList (which are final rules). For example, your activity can prevent users from adding rows after reaching a limit, or can compute additional properties for the page.

To override the default behavior when a user deletes a row from the array, identify the second key part of an activity to be called. Design your activity to accept the same parameters as the default activity Work-.RemoveFromPageGroup or Work-.RemoveFromPageList (which are final rules). For example, your activity can require that at least one row remains, or that users can't delete the first row.

When you first create a Row Repeat layout, a three-by-three table appears. Typically, cells in the top row present column labels, but these cells can also hold other property values (not from the embedded Page List or Page Group pages). Cells in the bottom row are typically used to present the Delete Row icon (
), but can also hold other property values (not from the embedded Page List or Page Group pages).
At runtime, the middle row appears once for each page. By default, users can add, append, and delete rows at runtime. You can change this default behavior:
) that appears at the bottom left of the third row. You can also delete the column containing this row.) that appears in the right of the second row. You can't delete the top or bottom rows; if they are not needed, you can apply a style that makes them not visible at runtime.
Optionally, you can use button controls or URL controls on the repeating layout rather than the standard icons for Add Row and Delete Row icons. The icon, button, or URL control can appear anywhere in the row.
When a repeating layout is based on a Page Group property and users click the Add Row icon () to append a new row, or press the Enter key to insert a new row, the system requires a subscript value for the new page.
In a Page Group property, the embedded text property pxSubscript acts as a unique identifier for the pages. This value may also be present in another property found on each page. As a best practice for usability, present the pxSubscript property (as a read-only value) in the left column of each row.
In some cases, the set of allowable values for subscripts are limited to a predefined static list, such as the codes for the 50 states of the United States (AL for Alabama through WY for Wyoming). In other cases, the set of allowable values for subscripts is unpredictable and effectively unrestricted, though each value must be a valid Java identifier. For example, a home insurance policy may contain a Page Group property with a page for each insured property, with the property identified by a government-issued code.
The Pega 7 Platform includes standard rules that support both situations. Your application can override the standard rules to allow users to enter or select a subscript value.
Page Group. Include only one input field on the section display. For example, if there are only a few allowed pxSubscript values, you can present the unused values as a set of radio buttons.Page Group.Local List or Remote List on the General tab of the new property. Then, complete the table fields, to enumerate the allowable values as a Local List, or define a Remote List that assembles the values dynamically.Note: At runtime, the system controls the order of rows presented for a Page Group property. After you append or insert a new row, it may be re-sorted to a different position after the Submit is complete.
