Description:

first of all, thanks for this awesome package

i can't get selected values tags in edit article

my form() method like
$form->multipleSelect('tags', 'Tags')->options(Tag::all()->pluck('name', 'id'));

and in Article Model, the relation method like
public function tags(){ return $this->belongsToMany('App\Tag')->select('id','name')->withTimestamps(); }

when i press edit button for any article, some fields working fine like 'title', 'description' but input tags field doesn't show selected tags for this article, just show all tags which come from Tag::all(), the input tags selected empty

how i can solve this proplem?

I had problems similar problems. I moved to explicit declaration and it works. Like so:

$form
    ->multipleSelect('tags', 'Tags')
    ->ajax('/api/list/tags')
    ->options(function() { return $this->tags->pluck('name', 'id'); });
