• Fix Version/s: 7.1.0 M1, 7.1.X, Master
• Component/s: Forms
• Labels:

• Git Pull Request: https://github.com/pedroqueiroz/liferay-portal/pull/98

Steps to reproduce:

1. Setup a Liferay bundle from a version where Drag and Drop was not implemented.
2. Go to Content > Forms
3. Add a Form
4. Add 5 fields in 3 columns following the layout: 1 - 3 - 1
5. Save form
6. Upgrade Bundle to Master
7. Go to Content, Forms and open the form you created in step 3

Expected result:
Although you can no longer add more than a field to one column, you still can edit the form and it should be visually ok.

Actual result:
The column with three fields looks messy, making it impossible to edit the fields.
