Is it possible to set a boolean html attribute (not property) with compose? attr("name", true.unsafeCast<String>()) sets it as name="", whereas it should set it as just name with no empty string value.

Isn't the convention for flag properties to do

$name="$name"

?

Haven't tried that yet, will give it a go and report back

attr("name", "true")

?

Nope, that one is read as true even if you pass in false value

I believe it’s because of this behaviour of

setAttribute

Setting

checked

attribute on input element. Here's the end result I'm chasing:

<input type="checkbox" checked></input>

We will take a look how to manage it.

Yeah, but it's kinda ugly 😀

Correct me if I'm wrong but boolean attribute with space is actually by spec a valid way to switch it "on". Not saying we shouldn't discuss API improvements, just want to see the whole picture

That might be true by spec, but many web frameworks don't follow it and demand empty attr without a value to work
