Need to add input field on click of "+" button

[Former Member]

Dear Experts.

Can any one let me know how to add new input field on click of "+" button and remove the same on click of "-" button.

1)Initially i've created view with one input field and one button icon"+" as shown below

2)And following is the code which has been written on "+"button action

METHOD onactionadd .
  DATA lo_nd_user_name TYPE REF TO if_wd_context_node.
  DATA lo_el_user_name  TYPE REF TO if_wd_context_element.
  DATA ls_user_name       TYPE wd_this->element_user_name.

*   navigate from <CONTEXT> to <USER_NAME> via lead selection
  lo_nd_user_name = wd_context->get_child_node( name = wd_this->wdctx_user_name ).

*   get element via lead selection
  lo_el_user_name = lo_nd_user_name->create_element( ).

*  ls_user_name-is_visible = 'X'.

  lo_el_user_name->set_attribute( EXPORTING name =  `USER_ID`  value = 'test' ).
  lo_el_user_name->set_attribute( EXPORTING name =  `IS_VISIBLE` value = 'X' ).

  CALL METHOD lo_nd_user_name->create_element( RECEIVING element = lo_el_user_name ).

  lo_nd_user_name->bind_element(
    EXPORTING
      new_item             = lo_el_user_name    " List of Elements or Model Data
      set_initial_elements = abap_false
          " If TRUE, Set Initial Elements Otherwise Add
*      index                =     " Index of Context Element
*    RECEIVING
*      element              =     " Web Dynpro: Interface for Context Nodes
  ).

ENDMETHOD.

3)Following is the output.On click of "+" button it does not add new input field.

Hi,

You could use the RowRepeater UI element to achieve this.

Hi,

Create a Row Repeater UI element, then create a Transparent Container and place the UI elements you would like to repeat, then bind those to the Row Repeater Data source Node.
