Custom HTML Form Templates
By default, online case forms match the style of your NetSuite website. However, with online HTML form templates, you can customize your online forms and match the style of your online forms to your website.
Online form templates are HTML documents you create outside of NetSuite and then upload to your NetSuite File Cabinet for use with online forms.
Note:
You can use HTML form templates only if you have the Marketing Automation feature enabled. Administrators can enable this feature at Setup > Company > Enable Features > CRM.
