# Context Object

Using Context Objects allows to set dynamic context on the Form. Merge Fields from Context Objects can be used everywhere on the Form: as Default Value, Title, Condition and any other input on the Form Item.

Expend "Context" panel (1):

* Context Objects (2)- objects that have sense in current form context
* Context Field (3)- fields of selected context object
* Merge Fields (4)- resulting code of field to be used

Select the Context Object, select required field, copy the Merge Field value to use it in any place in the form:
