Star rating widget: Unable to edit its labels in the form designer

My next issue is with this same form in the Designer. I have a star rating widget that I would like to make the lable wider but when I go into the designer I don't see that element. I only see part of my form, not the complete form so I can't edit that label. How can I make that section of my form appear in the Designer?

Unfortunately, the form designer doesn't show widgets in the form. But, you can edit the label using the form builder. I understand that you want to increase the label's width, right?

One way to do this is changing the label position to the top.

The other way would be injecting the following custom CSS code to your form.

.form-label.form-label-auto {
   min-width: 300px !important;
}

This would be the result: 

Hope this helps.
