I think this would be really awesome! We might have to go with the "mixed" mode you mentioned as the default since we'd be introducing a breaking change otherwise, but allowing the regular <select multiple>
style wouldn't be a problem if it was behind a property.
Where I can to get your extension? Please share it with community.
Where can we get a preview of this extension to test it?
@Caffeinix Awesome, I'd be interested to look at this code as well. Can you share it?
I have written an extension to
IronMultiSelectableBehavior
that implements a more general and traditional form of multi-select, similar to how multi-select works in most desktop applications. The behavior is as follows:My implementation is small (43 source lines) and works by extending
IronMultiSelectableBehavior
and overriding two functions,_activateHandler
and_toggleSelected
. The_activateHandler
implementation just records the keyboard modifiers and then callsIronMultiSelectableBehavior
's version._toggleSelected
is where the actual logic is implemented.My implementation does not support a "mixed" mode where an unmodified tap will toggle the selection state like
IronMultiSelectableBehavior
, but a shift-click will extend the selection. Such a thing would be relatively easy to add if it were desired, but it would increase the complexity somewhat.This PR would fix https://github.com/PolymerElements/iron-selector/issues/38.
Thoughts?
