Alfresco: Iterating over a map (containing a list) in ftl

Iterating over a map - Map<String,List<String>> in FTL file:

Sample JS/Controller file:

var code = "200";

var status = "status";

var desc = "Test";

var data = {

  "key1" : ["abc.pdf","xyz.pdf"],

 "key2" : ["pqr.pdf","stu.pdf"]

}

model.code = code;

model.status = status;

model.desc = desc;

model.data=data;

Ftl file:

{

   "code":"${code}",

   "status":"${status}",

   "desc":"${desc}",

  "data": {

         <#list data?keys as v>

         "${v}" : [

         <#assign account = data[v] >

              <#list account  as x>

                    "${x}"<#if x_has_next>,</#if>

           </#list>

              ]<#if v_has_next>,</#if>

       </#list>

  }
