<select multiple ng-options> do not support default/empty option

[martin-g]

http://docs.angularjs.org/api/ng.directive:select shows an example (Color (null allowed)) of a select with ng-options and an option with empty value.

At http://plnkr.co/edit/dMKSt7P4ZPcWgBkpGvPI?p=preview I have an example that shows the functionality stops working if I add 'multiple' attribute to the select.

It also has plain select (not managed by Angular) that shows the empty value is supported for select.multiple.

Here is the plunkr for the fix showing it works - http://plnkr.co/edit/jDijgjJ0EZLFUGIkTKDs?p=preview

Confirmed!
Looks as desired!

Hi @martin-g,
as I think over it, this does not make sense.

In a drop down box, you need an additional element to unselect a previously selected value.
However, in a multiple select, you are able to unselect any element by pressing Ctrl+Click (Windows) or Command+Click (Mac). This should work in any browser and is the default behavior of HTML.

So why do you need that additional entry, what is your use case?

Closing this for now. Please comment if you have a usecase that I overlooked.

Hi @tbosch ,

I had to use it in a mobile/phone application.
It is not so easy to use Ctrl there.

C'mon, don't ignore the UX for mobile applications!

Hi,
mobile browsers have their own UI for select multiple.

I didn't check older browsers. If they don't do what you need you would need to create a workaround for them, as this would be a browser bug.
