Dashboard like meta boxes in my plugin – how to save their position and open/clo

Hello,

I am trying to mimic the dashboard meta boxes UI in my WP plugin – the small metaboxes. I have already styled them and also the drag & drop feature works as I loaded the following script and style:

wp_enqueue_style('dashboard');
wp_enqueue_script('dashboard');

However I also would like to save my custom “postboxes” position (order) and also the open/close state.

Any ideas how could this be achieved?

Thanks.
