In v3 version routing, routes and tabs are set at the same time, but the routes in routes cannot be used. Why?

It is not supported, just put what you have in routes as separate routes

thanks,Another question
{{#each items}}
{{#js_if “this.info === ‘one’”}}one{{/js_if}}
{{/each}}
but js_if is not valid. How do you handle this? Thanks again!
