In this post UI elements like a Label and an input field is created dynamically and the input field is bound a context attribute designed statically.
Create a component and a context attribute.
The layout is FLOW Layout.
To dynamically add UI elements the method WDDOMODIFYVIEW can be used.
Put the below code to create a label and an input element.

METHOD wddomodifyview .
DATA :
lr_root_element TYPE REF TO if_wd_view_element,
lr_container TYPE REF TO cl_wd_uielement_container,
lr_label TYPE REF TO cl_wd_label,

* Creating an Input field

CALL METHOD lr_container->add_child
EXPORTING

ENDIF.
ENDMETHOD.
Create an application and test.
