Hi Munna,
When you select the first dropdown value yes, just you need to hide the dropdown field.
Please follow the steps:
Step 1: Create a Z class with interface IF_CHTMLB_FORM_ITERATOR in SE24 tcode.
Step2: Redefine the method RENDER_CELL_START of interface IF_CHTMLB_FORM_ITERATOR.
Add code similar to liek this,
* test by tdk
DATA: lv_html TYPE string.
CASE iv_binding_string.
WHEN '//BTCUSTOMERH/STRUCT.ZZCUSTOMER_H1008'. ( Specify your attribute along with context node)
IF iv_element_name = 'inputfield'.
CREATE OBJECT lv_bee.
ev_replacement_bee = lv_bee.
ENDIF.
ENDCASE.
Step 3:
Change the .HTM view page as shown below. Before setting the iterator check for your field first field attribute value.
Let me know still if you face any issues with this codes.
Best Regards,
Dharmakasi.
