Hi All, how can we make field label name in lower case in suitelet script?

There is a hard set of Label field to uppercase in the Suitelet and unfortunately we don't have any label property provided by NetSuite to change it to other cases. I tried to change the "text-transform" property to lowercase by inspecting the element and the field label has changed in the UI. If you can manage to change the "text-transform" property in the "CSS class" set by NetSuite through client script , then probably it should work. Other alternative could be to use an HTML layer on Suitelet instead of using the serverWidget fields

I tried test-transform but it is not working in script

okay, then probably you need to go through the HTML approach instead of using the serverWidget field.

Yes
