How to make an optional empty attribute?

[Riateche]

I need something like this:

input type="radio" name="f" value="a" checked=(value == 'a');
input type="radio" name="f" value="b" checked=(value == 'b');

This doesn't work because it just generates checked="true" or checked="false". I can work around it like this:

input type="radio" name="f" value="a" checked=[if value == 'a' { Some("") } else { None }];

It generates checked="" if the value matches and nothing otherwise, so it technically works, but it's inconvenient and it would be cleaner to generate an empty attribute.

It would be nice if checked=[value == 'a'] was rendered to checked or nothing.

Hi @Riateche, sorry for the delay 😄

Does this work?

input type="radio" name="f" value="a" checked[value == 'a'];

i.e. remove the = from checked.

On that note: I notice that the optional attributes section is on a different page to the other splices and toggles. I see how that can be confusing. So I'm happy to accept a PR that moves them together.
