arrays - Create "object" in freemarker only (no JAVA etc)? -

after reading freemarker documentation , googling don't see how can build test object (like associated, multilevel array) in freemarker only.

so like:

<#assign seq=["a","b","c"]> 

but in more depth - (pseudo):

        aa ab ac ad    b      ba bb bc    c      ca cb cc cd ce 

is possible in freemarker (as front-end dev waiting back-end guys finish need work on , not use bare arrays)?

tnx

that's not multi-level array, because each nested array has name ("a", "b", "c"). closest can think of is:

<#assign foo = {     "a": ["aa", "ab", "ac", "ad"],     "b": ["ba", "bb", "bc"],     "c": ["ca", "cb", "cc", "cd", "ce"] }> 

but there have utilized ftl hash literals keep key order. without that:

<#assign foo = [     {"name" : "a", "value": [ "aa", "ab", "ac", "ad"]},     {"name" : "b", "value": [ "ba", "bb", "bc"]},     {"name" : "c", "value": [ "ca", "cb", "cc", "cd", "ce"]} ]>
