vue-virtual-scroll-list VS Fela

How would it work with vue virtual scroll list The library requires a single items array from what I understand, do I have to do anything special to make it work with this library

These popular components allow for quick scrolling through large amounts of data in Vue apps, but do come with a caveat; Vue-virtual-scroller and Vue-virtual-scroll-list don’t deal with dynamic heights unless you hardcode them. If you want to test it out, there is a playground available for Vue Virtual Scroller here.

[Fela](https://fela.js.org/) and [Griffel](https://github.com/microsoft/griffel) are also not bad choice.

Speaking of libraries and implementation. I implemented themes for white label (and not only) on UI via styles as a function of state on UI. I used https://fela.js.org/ for this. So basically, when a React app initializes, a part of the state is initialized (via identity of a user, like email they log in or meta info, or additional API call, or via URL) with a value telling if it's a partner X vs partner Y vs your own brand. Then the styles that have colours, backgrounds, borders, box-shadows, fonts are applied by fela. So I created a bunch of styled components like buttons, toggles, styled divs, etc and each of them has access to that piece of state holding the UI theme, and depending on that theme, it will apply CSS classes in the runtime. You can use the same mechanism to implement multiple themes for your own brand (not just light/dark modes). The only thing you need to manually code is a JSON spec for themes like:
