If you need to create an input field, for eg.

data lr_input_fld type ref to CL_WD_INPUT_FIELD.

lr_input_fld = CL_WD_INPUT_FIELD->NEW_INPUT_FIELD(
                       EXPORTING
                            BIND_VALUE = <node_path> ).

Similarly for each UI element, there is an associated class having a NEW_<UI_ELEMENT> method.

Check the class and the method for the signature.

You will also need to use SET_LAYOUT_DATA()

Eg, if you want to add the fields in a group that has matrix layout, you will first need to create CL_WD_MATRIX_HEAD_DATA->NEW_MATRIX_HEAD_DATA and pass the return parameter to SET_LAYOUT_DATA().

If adding in the Group on the view, get refernce of the group using view->get_element(<element_name>)

and then ADD_CHILD()

Note that you have the reference of the view in WDDOMODIFY method
