1. The template string only uses backticks, but your string uses both single quotes and backticks.

The

2. replacement value (route.params.id) refers to aroutevariable that appears to be undefined in your example. I think you want to accessthis.$route, so the actual replacement should bethis.$route.params.id

itemsThe array should look like this:

export default { data() { return { items: [ { title: 'List User', url: `/user/function/listUser/${this.$route.params.id}` }, { title: 'structure User', url: `/user/function/structUser/${this.$route.params.id}` } ] } } }

Demo

This is an example

`/user/function/structUser/${this.$route.params.id}`

Also, maybe try using it inside acomputedas it may not be a computed property.
