Non Editable/Editable Text in TextEditor - WD ABAP

Hi,

In TextEditor, I need to show few lines of text in read only mode or not to be edited and allow to add text below.

In other words, previously entered text shouldn't be allowed to edit and allow the user to enter fresh text in the same TextEditor.

May I know how to achieve this requirement in SAP WebDynpro.

Thanks,

Thiyagarajan
