MifMenu - "detach" method?

hey moro

actually, I ran into quite a problem with MifMenu. maybe you could help me out.

I am working on images data grid that is similar to Windows Explorer's Thumbnails view. MifMenu is attached to every tile/square.

I need to be able to dynamically reconfigure menu items depending on number of tiles selected: if more than one tiles are hilighted - I want to have "Delete all selected" item in addition to "Delete" that is always there.

Here's my code:

        var itemMenu = {items:[]};

        itemMenu.items.push({
            name: 'Delete',
            onAction: function()
            {
                this.menu.el.fireEvent('deleteOne')
            }
        });

        if (this.options.selected.length > 1)
        {
            itemMenu.items.push({
                name: 'Delete all selected',
                onAction: function()
                {
                    this.menu.el.fireEvent('deleteAll')
                }
            });
        }

        var menu = new Mif.Menu(
            {
                list: itemMenu
            },
            {
            container: Mif.Menu.Container,
            options:{
                ...
            }
         });

         menu.attachTo(tile);

So menu is initialized with each click on a tile - this is done to reconfigure it and show "Delete all selected" item.

The problem is that menu.attach() method does not replace existing attached menu with the new one. As a result I have TWO overlapping menus.

Questions:

1. Is it possible to detach an existing menu from a tile?
2. Can menu.attach() method override menu that's been attached previously?

My preferred solution would be if you could add a new method that accepts new 'list' definition that contains new/updated items for the existing & attached menu.

This would enable me to write something like:

        var menu = new Mif.Menu(
            {
                list: OriginalMenuItems
            },
            {
            container: Mif.Menu.Container,
            options:{
                ...
            }
         });

         menu.attachTo(tile);

and later on trigger display using:

         menu.display({list: UpdatedMenuItems})

What do you think?

Thanks
