Creation of drop down for a field which is created using otr

Question

Hi experts
I have a requirement wherein i have to create a dropdown for a field which is added using otr (online text repository).
When i did an F2 on the field on the UI i found that it had no context node and attribute and the view in the component workbench did not have a configuration also. The coding for that field is done in the htm page of that view using otr.
For this field i need to create a dropdown (the dropdown values will be fixed). I thought it would be better to code in the method do_init_context.
Request you to help me out with the code for this requirement as i do not have any idea with regard to otr.
Thanks and regards

Hi Preeti,
1.You need to maintain a page attribute(dd_list_type) which is of table type to the htm page of your view.
2.Then in the set_models method of your view controller add the following code:
* Put the data into the view attribute
  view->set_attribute(
        name   = 'dd_list_type'        
        value  = lt_list_type ).
You can add OTR text list to the internal table lt_list_type.
3.Then add the following code to .htm
* ADDITIONAL CODING IN VIEW
<% data:           lr_listl_type  type ref to data.
   field-symbols: <list_type>   type table.
   get reference of dd_list_type into lr_list_type.
   assign lr_list_type->* to <list_type>.
%>
<htmlb:dropdownListBox id="ListType"
                       table = "<%= <list_type> %>"
                       selection = "<%=controller->gv_model_id %>"
                       nameOfKeyColumn = "KEY"
                       nameOfValueColumn = "VALUE"
                       />
