how can use multi select to edit a existin element, i can't fill the select with a database

You have to put the options inside your select from your database. Add selected for those which have to be selected and run the init code :

$(function () {
$('select').material_select();
});

But the options you will select and deslect won't match to the real select value because there is an issue. There is a PR to fix that.
