Unique ID settings

A unique ID attribute contains a value that is unique for an element. When an element with this attribute is created, the element is automatically assigned a unique ID. Typically, the unique ID is not editable.

Setting Name Description
Value Default Value The value of the unique ID attribute when a new element is added. You can edit this value before the element is saved.
  • You can include the number sign (#) in the default value. The number sign (#) is replaced by an integer that makes the attribute value unique when an element is created.
  • If the default value does not contain the number sign (#), a number sign (#) is added automatically to ensure that attribute values for new elements are unique.
  • If the default value field is empty and the Allow Empty Values check box is selected, the number sign (#) is not added.
  • You can use more than one number sign (#). If the default value is four number signs (####), when elements are created, the number signs are replaced with 0001, 0002, 0003, and so on.
