Text Areas
Use
In an HTML text area, users can create their own multiline text:
The input field can be locked against entry.
The text within a text area cannot be formatted.
Text areas can be used in Web forms, even with SAP Web AS 6.10 (via Support Package). See Note 434644.
Integration
To integrate HTML text areas in a Web form, mark a whole text node as Text area on the Web Attributes tab page (see:
Using Text Areas). The generated HTML code is then as follows:<text area NAME="(name of text node)"
ROWS="(value from input field Column/Width)"
COLS="(value from input field Lines/Height)"
DISABLED <!-- Only if Display is selected--> >
<!-- content of text node -->
</text area>
Unfortunately, the system cannot check whether the text area has enough room in the window in which the text node is output.
Features
Smart Forms can generate a text area from text elements, text modules, and include texts. Smart Forms generates HTML input fields before and after the
<TEXTAREA> tag. These fields have the type HIDDEN and the attributes of the Smart Form text are stored in them. These attributes are transferred with Submit:Transferred information when a text area is used in a Web form

Evaluating Form Input.Returning Changed Text to the Smart Form
In many applications, you want to integrate the text that was changed in a Web form back into a Smart Form in order to print the form with the changed text. This is no problem in the case of simple and group input types because you can pass the changed values to the form from the form interface.
You cannot, however, transfer a text node to the form interface or process or create a text element or text module from a Smart Forms API. If you want to use text created using a text area in your Smart Forms template, you have to work with
Include texts. You can modify an include text using the function module SAVE_TEXT so that the updated text is read when the text of the form is read again.
