admin-ui

Example app: https://pp0o4x40p0.codesandbox.io/#/posts/13

I just copied the last tab a couple of times and you'll see a scrollbar at the bottom.
What I expected: that the Tabs component would be scrollable and the application not to crash.
I think this is because the Tabs parent width is implicit instead of explicit.

Alert can't be closed because it has not modelValue.

Need to make similar demo like in docs https://vuestic.dev/en/ui-elements/alert#closeable

Hi, thanks for making such an awesome tool. Is it possbile to also add nestjs-query support? I saw there is nest-crud which is great, but IMHO a GraphQL API has many advantages over REST. It would be great if refine can support both nest-crud and nestjs-query.
Many thanks!
