@lovasoa That page contains an example of else if in handlebars. Since this library is compatible with the Handlebars syntax, you should be able to use it and things should Just Work.

No, it's not supported, that's why I opened this PR.

use handlebars::Handlebars;
use serde_json::json;
use std::error::Error;

fn main() -> Result<(), Box<dyn Error>> {
    let mut reg = Handlebars::new();
    println!(
        "{}",
        reg.render_template(
          "
          {{#if isActive}}
              active
          {{else if isInactive}}
             inactive
          {{else}}
             unknown
          {{/if}}
          ", &json!({"isInactive": true}))?
    );

    Ok(())
}

$ cargo run
             unknown

After a quick search, it seems that else-ifs are not present in the current testing suite.

There's an open issue for this: #12

As is, it is sadly not supported.
