Help creating a zimlet

Hello, I'm trying to create a menu zimlet for "Briefcase" where the user can create a custom Briefcase with a template and add sharing rights at the same time.

My first question is how I create a new briefcase, I have the parent id and name, but didn't find any way to create one. Can you please help or point me in the right direction?

Thanks in advance,
Vlad.

BTW, using the js api

Found a way to do this:

Code:

---

        var folder = {
                name:document.getElementById('client').value,
                'l':document.getElementById('folder_id').value,
                view:"document"
        };
        var jsonObj = {CreateFolderRequest:{
                _jsns:"urn:zimbraMail",
                folder:folder
        }};
        var searchParams = {
            jsonObj:jsonObj,
            asyncMode:true,
            callback:new AjxCallback(this, this.handleCreateBriefcase),
            errorCallback:new AjxCallback(this, this.handleCreateBriefcaseError)
    };
        appCtxt.getAppController().sendRequest(searchParams);

now my problem is how will I upload some default files there? Any tips?
