    Hi,
    Create attribute under view context. attribute name 'VISIBILE' of type WDUI_VISIBILITY.
    and add this code to your dropdown onaction.
    DATA lo_el_context TYPE REF TO if_wd_context_element.
          DATA ls_context TYPE wd_this->Element_context.
          DATA lv_visible TYPE wd_this->Element_context-visible.
    * get element via lead selection
          lo_el_context = wd_context->get_element( ).
    * set single attribute
          lo_el_context->set_attribute(
               name =  `VISIBLE`
               value = '2' ). // 0 - for none

  • Drop down in web UI

    HI
    I need a drop down in web UI pop up  so the user will select a value from the drop down and post it for the respective  event message .
    how can i configure this drop down in event message pop up
    Regards
    ravi

    Hello Ravi,
    There are two ways to configure with drop down menu.
    1) Via Control Parameters (This will defaulted to your value)
              - Create Control Parameters
              - Provide values to the Control Parameters
              - Define your event message parameter with parameter name equal to control parameters
              - Define event message parameter with parameter value and make sure you unchecked No Fixed Values
    2) Via Search Help
              - Define your own search help with the values you want and then assign that search help while defining event message with parameter value
    Please let me know if its not work for you.
    Thanks,

  • Creating Drop Down Lists in J2ME

    Hello all,
    I'm not an experienced programmer, and I fear that the rumours of posting a crie for help only to be set upon by hundreds of blood thirsty 'newbe' hunters may be true, but here goes none the less.
    Would love to know if any kind soul has hints on how to create drop down lists in J2ME, for selecting a option which would be able to relate to a database (Table).
    At the moment I'm using straight forward TextField entries, which is hardly convenient! :)
    Any help/comments/sweets appreciated!
    Cam

    Hi Cameron,
    Only MIDP 2.0 support drop down list. So if you currently coding in the MIDP 2.0 environment, here are the codings.
    String arr = new String[]{"Happy","Sad"};
    ChoiceGroup ch = new ChoiceGroup("Select Choice:",ChoiceGroup.POPUP,arr,null);
    append(ch);
    Hope this codes is helpful to you.
