You could send variables in map. For example:
package main
import (
"bytes"
"fmt"
"text/template"
)
func main() {
t, _ := template.New("hi").Parse("Hi {{.name}}")
var doc bytes.Buffer
t.Execute(&doc, map[string]string{"name": "Peter"})
fmt.Println(doc.String()) //Hi Peter
}

The . is defined in go code.
Please provide the snippet of your go code where the template is executed, something like the following codes:
t, _ := template.ParseFiles(tmpl + ".html")
t.Execute(w, data) // the data must feature the field "checked"
Or
templates.ExecuteTemplate(w, tmpl+".html", data) // the data must feature the field "checked"
You can pass any type(interface{}) to a functions that execute a template as "data". Usually it is a Struct or a Map[string]string.
How to set the checked Probably the "checked" is setted in the main.go at handler according to the posted form.
Read the docs and explain it better. Please
