当使用ajax填充项目时，Select2允许选择“错误的项目”

Question

Please check the image attached

I'm working with select2 4.0 and am populating items into the select by using ajax calls. All is working fine. I can do incremental search and this speeds a lot.

The problem is that select2 allows user to select this "temporary item" generated dynamically from what user writes in the box...

Does anyone know how should I disable selection of this item? Or at least validate in the button click that this item should not be selected...

Answer 1

I've reviewed the entire code and noticed I had these 2 options enabled in the select2 init. I removed them and now all is working fine.

tags: true,
tokenSeparators: [',', ' '], 

I must have left them copied from some example copied/pasted

Hope it can be useful for someone with same problem in future
