问题
I've been trying out the new Select2 v4.0 which has a lot of improvements. I'm mainly interested in the tags feature. I want to be able to search for tags via ajax and only be able to select a tag from the shown results and not be able to create new tags. The functionality is similar to StackOverflow - if you don't have the necessary reputation you can't create new tags, but you can still tag a question with existing tags.
Here's a jsfiddle with my code which is taken from the examples. In the example, you can create new tags which are what I want to limit. The user should be able to select tags only from the list that's retrieved from GitHub via ajax.
Does anybody know how to disable this functionality?
回答1:
This should work - in the initialization of select2, try returning undefined from the createTag function like so:
createTag: function(params) {
return undefined;
}

I've been struggling with this as well, but got it working after a few hours.
I had specified a few token seperators (because my visitors are allowed to create tags in a different spot in the website). Turns out the seperators are still applied even if the tags configuration is set to false.
Solution: tags: false and do NOT add a value for tokenSeperators. Keep multiple: true.
回答3:
You can disable tags by removing tags: true when initializing Select2. Or alternatively, setting tags: false when initializing Select2. Tags are only enabled if the tags option is truthy, which it is when you are passing in true.

I am not sure if I should add the following in here but as I was searching for the same issue google pointed me to this question. However I use an older version 3.x and this is how to achieve the same scenario for the 3.x versions.
Tested on version 3.5
createSearchChoice: function(params) {
return undefined;
}
