DropDown - With text explanation on the dropdown

Question

Hi,
I would like to get a drop down with explanation on the dropdown but on selection only key must be selected.
for eg . Here are the dropdown values
US  United States
AU  Australia
NZ  Newzeland
DE  Germany
when selected the dropdown field should contain only US or AU. Is there a way to achieve this.
Thanks

this all, of course depends on your context and which drop down element you choose to use.
If you bind your context as such.
DATA: lo_nd TYPE REF TO if_wd_context_node,
         lo_nd_info TYPE REF TO if_wd_context_node_info.
data: it_value_list TYPE wdr_context_attr_value_list,
          is_value like line of it_value_list.
data: iv_key type any,
iv_text type string.
lo_nd = wd_context->get_child_node( name = wd_this->wdctx_whatever ).
lo_nd_info = lo_nd->get_node_info( ).
select code text from somewhere into (iv_key, iv_text).
is_value-value = iv_key.
is_value-text = iv_text.
append is_value to it_value_list.
endselect.
lo_nd_info->set_attribute_value_set( name = 'COUNTRY' value_set = it_value_list ).
On your view use the DropdownByKey and bind the selected key property to the country attribute and check the KeyVisible field. Otherwise you can set it dynamically in the modifyview method and set the flag with CL_WD_DROPDOWN_BY_KEY->SET_KEY_VISIBLE.
hope this helps.
