AJAX Sub Form gives you the flexibility of dynamically loading a Subform by attaching a listener to other form field.
Unlike the generic Sub Form element found in the community edition, AJAX Sub Form gives you the flexibility of dynamically populating a Subform as the value it watches changes.
Data to load by the AJAX Subform
The target's form Load Binder will be executed to fetch record matched from the properties defined in AJAX Subform.

| ID | Element ID (By declaring as "view_existing_claim", a corresponding database table column "c_view_existing_claim" will be created) |
| Label | Element Label to be displayed to end user. |
| Form | Target Form to be loaded. Usage of Hash Variable The use of Hash Variables inside the target form is permissible but may be limited due to the nature of how the form is loaded.
