Hi Alfonso:

Can you solve Navigation List with n-level?

Hi Krishna,

I´m looking for an example like the one in the first link you sent, but a bit more complex. I would like to have more than 1 level on the navigation list, in that example just 1 level is being used.

Thank you !!

In this Example:

Context Node    :DATASOURCE

Recursion Node :DATASOURCE_RECURSION

Attributes          :TEXT

                         ENABLED

Bind TEXT to itemText property of Navigation List UI Element.

Bind ENABLED to enabled Property.

Bind the DATASOURCE node to itemSource property

Write this code in Supply Funtion of the context node DATASOURCE and debug, so that u can understand and apply for your requirement.

   DATA lo_el_datasource TYPE REF TO if_wd_context_element.

   DATA ls_datasource    TYPE wd_this->element_datasource.

   DATA lt_datasource    TYPE wd_this->elements_datasource.

   DATA parent_node      TYPE REF TO if_wd_context_node.

   DATA name TYPE string.

   parent_node = parent_element->get_node( ).

   IF parent_node->get_node_info( ) = node->get_node_info( ).

     parent_element->get_attribute( EXPORTING name = 'TEXT'

                                    IMPORTING value = name ).

   ELSE.

* Adding main elements to the navigation list

     ls_datasource-text = 'Nav List 1'.

     APPEND ls_datasource TO lt_datasource.

     CLEAR ls_datasource.

     ls_datasource-text = 'Nav List 2'.

     APPEND ls_datasource TO lt_datasource.

     CLEAR ls_datasource.

     ls_datasource-text = 'Nav List 3'.

     APPEND ls_datasource TO lt_datasource.

     CLEAR ls_datasource.

     ls_datasource-text = 'Nav List 4'.

     ls_datasource-enabled = abap_true.

     APPEND ls_datasource TO lt_datasource.

     CLEAR ls_datasource.

   ENDIF.

* Adding sub elements to the navigation list

   IF name = 'Nav List 1'.

     ls_datasource-text = 'Hi'.

     APPEND ls_datasource TO lt_datasource.

     CLEAR ls_datasource.

     ls_datasource-text = 'Bye'.

     APPEND ls_datasource TO lt_datasource.

     CLEAR ls_datasource.

   ENDIF.

   IF name = 'Hi'.

     ls_datasource-text = 'Hello'.

     APPEND ls_datasource TO lt_datasource.

     CLEAR ls_datasource.

     ls_datasource-text = 'Bolo'.

     APPEND ls_datasource TO lt_datasource.

     CLEAR ls_datasource.

   ENDIF.

* Bind the data to the node

   node->bind_table( lt_datasource ).

   REFRESH lt_datasource.
