Switch

templ uses standard Go switch statements which can be used to conditionally render components and elements.

component.templ

package main

templ userTypeDisplay(userType string) {
	switch userType {
		case "test":
			<span>{ "Test user" }</span>
		case "admin":
			<span>{ "Admin user" }</span>
		default:
			<span>{ "Unknown user" }</span>
	}
}

main.go

package main

import (
	"context"
	"os"
)

func main() {
	userTypeDisplay("Other").Render(context.Background(), os.Stdout)
}

Output

<span>
 Unknown user
</span>
