In order to add form field to the schema, here is the workflow:
1. Highlight the form field which you want to add a form field after that.
2. Search the form field and click it
3. It prompt the Edit FormField box to enter other metatdata such as field number, part, ..., etc.
4. Click on save button.
In reality, most of our forms require lots of form field which is longer than the height of the computer screen. After step 2 is done, users need to scroll all the way down in order to enter metadata for step 3. It's becoming very inefficient for the form manager to scroll down repeatedly for each form field added. Once Step 2 is done, the screen should be repositioned to the Edit FormField pop-up box.
