The process of creating a form design for LiveCycle Forms ES is identical to creating any other type of form design. However, when you create a form design for LiveCycle Forms ES, the same form design can be used to render PDF or HTML forms.
Using LiveCycle Forms ES, you can post PDF and HTML forms on the Internet or an intranet. When LiveCycle Forms ES renders an HTML form, the form typically opens in a web browser. When LiveCycle Forms ES renders a PDF form, the form may open directly in Acrobat or Adobe Reader, depending on the settings of Acrobat or Adobe Reader on the user’s computer.
When you distribute forms in a web environment, you must consider the limitations of the environment. For example, some of the features that you can assign to form designs by using LiveCycle Designer ES are not supported in a web environment, and different web browsers display the same objects in different ways.
Furthermore, some form capabilities are not directly supported by web browsers or HTML technology. The full range of form capabilities is available only when a PDF form is opened using Acrobat or Adobe Reader.
For information about the properties supported by different web browsers, go to the Adobe documentation website at https://www.adobe.com/go/learn_lc_documentation and navigate to Transformation Reference.
