# Editing rule cells

Rule cells define the matching criteria for the rules.

Most rule cells require you to insert elements of specific types:

- When you select the cell, the Resources pane on the left shows the types of elements that you can insert.
- You can drag and drop elements from the Resources pane, from another cell, or even between tabs.
- Define detailed sets of matching criteria in the Definitions dialog box for the Source, Destination, and Service cells.
- You can create new elements in the Resources pane.

To edit rule cells that do not accept elements, right-click the cell and select an item from the right-click menu.
