PSA: Do NOT disable the options API in your application

[kai42069]

Hey Peeps

I found out the hard way (2 days of trying to figure out WHY my application [specifically this multiselect] broke) when I updated dependencies..

https://vuejs.org/api/compile-time-flags#VUE_OPTIONS_API

VUE_OPTIONS_API: 'false' // Multiselect will die

Weirdly though, it only started to die once my vitejs/plugin-vue version exceeded 5.2.1.

"@vitejs/plugin-vue": "5.2.1" // Fine
"@vitejs/plugin-vue": "5.2.2" // Issues started

Hope I saved you all some time/anguish.

-_- Kai

We had a very similar issue, I'm AFK rn, but I'll check soon

This is GOLD!

Thank you, @kai42069 and @RyanGst. This just saved us MANY hours of work I suspect.

Maybe there is a way to add this to some known issues in the docs. Is there such a section in the docs. I will take a look.

PR welcome, @shentao?

That's interesting! It must be because the multiselect itself is written with the Options API (this is a rather legacy project after all). I'm surprised that even though it's already precompiled (importing from /dist), it's still affected by the Vue compile flag.

A PR to the README is absolutely welcome!
