The tree picker is a special reference lookup that you can add as an attribute to a
form. Add the tree picker to the classic environment or to workspaces.

The tree picker is a special reference lookup for the following items.

* Configuration Items (CIs) for a field that depends on another CI field.
* Reference elements for any hierarchical table. A hierarchical table is any table that has a parent field pointing back at itself.
* Values for a user reference that depends on the group.
* **[Add the tree picker attribute](https://www.servicenow.com/docs/_wxFAuMFB9Yr4YUPxYwMfQ)**   
  A limit of 1000 has been placed on the number of nodes returned to the tree picker. This limit is configurable with the glide.ui.group_heirarchy.max_nodes property.
