# List Action
The list node is used to work with lists. When a list node is reached an action can be performed on the list defined by the list node.
When a list node is created, WEM presents a popup where the list for which the action should take place is selected:
The properties and exits of a list node depend on the type of action that should be performed. The property table below presents all options:
| Item | Description | Exits |
| ------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ----------------------------------------------------------------------------------------------------------- |
| **Name** | This is set to the action that is performed on the specified list. This property is set by WEM and cannot be changed. | N/A |
| **Limit to parent** | (only for goto row actions)
When turned on, only direct children of the current row are considered. When turned off, all rows of this list are considered, also those of other parent rows.
