Conditional “multiple” attribute in <input type=“file”>

[tonylampada]

I need an upload form field that may or may not allow the user to select more than one file.
I expected to be able to accomplish that with something as simple as:

<input type="file" ng-multiple="allow_multiple">

But that doesn't work.

I asked about it on stackoverflow but didn't get the solution I was looking for.
Are we missing a feature here?

Binding to multiple is currently not supported. It was forbidden because it caused issues with the select directive. Actually, input type="file" is also not supported, and probably won't be in angular 1.x, see #1375 (comment). So I am gonna close this issue. That said, there's nothing in core stopping you from implementing your own ng-multiple directive for type="file" or a complete upload directive. (There are also several 3rd party modules)

@tonylampada, I don't have my desktop at reach, but could try using ng-attr-multiple='{{allow_multiple}}' instead?
