Never mind, I solved it.
Just create dublicate of buttons templates with another id (btn-add-2 & btn-remove-2 in gd-mylist\template), hook it in gd-mylist-code.php in $templates_html = array(… Than dublicate action and function creating add/remove buttons. Use different actions to call myList’s button in each case.
In js/gd-script.js dublicate all srtings which contain “$(“#mylist-” and change for “$(“#mylist-2-“.
That’s all. Thans for plugin, it’s realy great!
