Is there an ability to include multiple classes dynamically with one statement?

[zoryamba]

I can include some class conditionally, kinda:

<a
    class=("active", move || index.get() == i)
>

But for multiple classes with same condition I must repeat the condition over and over:

<a
    class=("active", move || index.get() == i)
    class=("dark", move || index.get() == i)
>

Wouldn't it be useful to specify multiple classes at once kinda:

<a
    class=("active dark", move || index.get() == i)
>

I know i can combine classes with CSS, but just wondering, why isn't it supported? Is there any reasons to restrict this?

Here's an example with three different ways to do what you're asking. Take your pick!

let index = RwSignal::new(0);
let i = 0;

let condition = move || index.get() == i;

view! {
    <div class=(["active", "dark"], move || index.get() == i)></div>
    <div class:active=condition class:dark=condition></div>
    <div class=move || (index.get() == i).then_some("active dark")></div>
}
