Row expander is a component in the Publisher infrastructure that is used to show additional details on a selected row in a list.

If configured and linked to a Publisher list, a row expander enables you to view additional details on a list item you have clicked. The results are displayed in the list itself, in an expanded list row.

Row expander should only be used to display additional information that is relevant to most users. For example, in a report on persons, the row expander is ideal to display a photo and contact information.

Do not use the row expander to display a lot of detailed information. Use the Details page instead.
For example, in a report on orders, you can use a row expander to display a name and description and have the rest of the detailed information displayed on the Details page.

If you have configured both a row expander and a Details page, the More details link is displayed on the row expander. When a user clicks the link, the Details page is displayed.
