Question

I get a json from database, then load dynamically a template and apply that json. The data stored in this variable is self-referenced (the typical id – parent_id).
I’m unable to do a recursion of that data.

the json:

var my_json = {"modules":[
    {
        "id_modules": "1",
        "id_modules_parent": "0",
        "mod_name": "mod 1",
        "sub_modules": [
            {
                "id_modules": "2",
                "id_modules_parent": "1",
                "mod_name": "mod 1a",
                "sub_modules": ""
            },
            {
                "id_modules": "3",
                "id_modules_parent": "1",
                "mod_name": "mod 1b",
                "sub_modules": ""
            }
        ]
    },
    {
        "id_modules": "4",
        "id_modules_parent": "0",
        "mod_name": "mod 2",
        "sub_modules": [
            {
                "id_modules": "5",
                "id_modules_parent": "4",
                "mod_name": "mod 2a",
                "sub_modules": [
                    {
                        "id_modules": "7",
                        "id_modules_parent": "5",
                        "mod_name": "mod 2aa",
                        "sub_modules": ""
                    }
                ]
            },
            {
                "id_modules": "6",
                "id_modules_parent": "4",
                "mod_name": "mod 2b",
                "sub_modules": ""
            }
        ]
    }
]}

This is how I render the template:

$.get("template_file.txt", function(template)
{
    $.tmpl(template, my_json).appendTo("#some_div");
});

and finally the template (template_file.txt):

<ul class="modules_ul">
    {{each(i, module) modules}}
        <li>${module.mod_name}</li>
        {{each(j, submodule) module.sub_modules}}

            {{tmpl(submodule) ".modules_ul" }} //what goes here?

        {{/each}}
    {{/each}}
</ul>

Can anybody help me? Thanks in advance!

Edit:
added a jsfiddle to play around

It should be like this

<ul class="modules_ul">
    {{each(i, module) modules}}
        <li>${module.mod_name}</li>
        {{if module.sub_modules}}
            {{tmpl(module.sub_modules) "template_name"}}
        {{/if}}
    {{/each}}
</ul>
