This function creates a form instance manually for a specific form definition.

You should navigate to the Run - Form Instances page and click on the Action - Create menu option. 

The Create Form Instance popup window appears for configuration, as shown below. You must select the form definition from the drop-down list. You may use the search filter buttons to view the definition list sorted by the last modified date or by name. You'll need to manually click the Generate button for the new instance name OR provide a unique form instance name. Click on the Create button to confirm. 

The new form instance is created, and the confirmation message is displayed in the top right-hand corner, as shown below. 

Select the new form instance from the list and click on the Actions - Edit menu option. 

The new form instance is rendered on the new page for submission. Alternatively, a previously submitted form instance can be selected for editing this way.
