Select should return a single value if multiple is false

[RomainMazB]

🚀 Feature request

The actual Zag API for the Select state machine always returns an array, despite the fact multiple option is false or true. Even when no value is selected, it returns a non-falsy value(Boolean([]) === true).

🧱 Problem Statement / Justification

The most basic HTML5 select tag returns a single value when the multiple attribute is not set.
And you need extra code to retrieve the array of selected values when multiple attribute is set.
Example as a JSFiddle

The HTML W3C Standards states that the value returns the value of the first selected item, if any, or the empty string if there is no selected item.

With this in mind, my expectations for the Zag Select state machine would have been to return a basic string value in its most basic form, which is not the case.

✅ Proposed solution or API

value: string[]|string 🤘

↩️ Alternatives

The current only alternative is to "override" in the project component the state machine to select the value[0] when multiple is false. I don't feel comfortable with this because I don't want to add extra code to actually "regress" the state machine to its most basic form.
Extra code is for enhancement, not regression.
