Tags front-end edit page

hello,

I’m using event-editor.php template to modify the “edit” and “new” event page,
i add 3 tags to event(from em-event option page), so in back-end editor in creation or modification events it’s possible to choose from these 3 tags to add to event.

i would like to do the same in front-end editor (event-editor.php),
how can i add tags in this view?

$EM_Event->event-tags should contain the event tags, but how can I make this variable editable?
