hello Sagar,
u r dynamically generating dropdowns in ur view say VIEW1.U must be generating ur UI dropdowns on click of the button under a trnsparent container with a particular DROP DOWN INDEX ID .
in ur onActionAdd method if u r generating drop downs with ID say DD101, DD102, DD103 and so on ...
thn in ur close button , u need to use the method REMOVE_CHILD_NODE and try to remove the dropdowns with same index .
u cn take reference of this code :
DATA :
    DATA:
            lr_node_info     TYPE REF TO if_wd_context_node_info ,
            lr_node          TYPE REF TO if_wd_context_node,
            dd_indx_id       TYPE string .
CONCATENATE lv_node wd_this->count_sysdel INTO lv_node.
        dd_indx_id = 'DD_1'.
        wd_this->count_sysdel = wd_this->count_sysdel + 1.
        wd_this->count_dd_sys = wd_this->count_dd_sys + 1.
        CONCATENATE dd_indx_id wd_this->count_dd_sys INTO dd_indx_id.
        lr_node = wd_context->get_child_node( name = lv_node ).
        lr_node->invalidate( ).
        CALL METHOD lr_node_info->remove_child_node
          EXPORTING
            name = lv_node.
        lo_drdwn = lo_container->remove_child( id = dd_indx_id ).
here lv_node is the name of ur node , I am using count_sysdel of type NUM and concatenate statement
to provide unique names to the generated node.
u cn declare it under the attributes tab .
u can have dd_indx_id = 'DD_1' and increment count each time using
wd_this->count_dd_sys  which is another counter .
do revert back if u need any assitance ,it shud help .
