open the filemanager in modal window

Hello,

I'm having big troubles trying to open the filemanger (i'm using elFinder) in a modal window when clicking the "Browse" button.

I've found that code on the web but it seems it's not working for me :

    CKEDITOR.on('dialogDefinition', function(event) {
    var editor = event.editor;
    var dialogDefinition = event.data.definition;
    console.log(event.editor);
    var dialogName = event.data.name;

    var tabCount = dialogDefinition.contents.length;
    for (var i = 0; i < tabCount; i++) {
        var browseButton = dialogDefinition.contents[i].get('browse');

        if (browseButton !== null) {
            browseButton.hidden = false;
            browseButton.onClick = function(dialog, i) {
                editor._.filebrowserSe = this;
                jQuery('<div \>').dialog({modal: true, width: "80%", title: "Insert image", zIndex: 99999,
                    create: function(event, ui) {
                        jQuery(this).elfinder({
                            resizable: false,
                            url: "/path/to/connector.php",
                            getFileCallback: function(url) {
                                CKEDITOR.tools.callFunction(editor._.filebrowserFn, url);
                                jQuery('a.ui-dialog-titlebar-close[role="button"]').click()
                            }
                        }).elfinder('instance')
                    }
                })
            }
        }
    }
});

Is there any chance to open the filemanager (whatever it is ckfinder, simogeo filemanager, elfinder..) in a new modal window ?

thanks for your help
