Data Structure in Golang that will be passed to a template to render a side navigation bar based on bootstrap

gistfile1.go

package main

import "fmt"

type NavBar struct {
	SpanDefault int
	Content []Category
}
type Category struct {
    Name string
	Content []SubCategory
}
type SubCategory string

    var firstSubCat SubCategory = "link one"
    var secondSubCat SubCategory = "link two"
var firstCategory = Category{"Category1", []SubCategory{firstSubCat, secondSubCat}}
	var p = NavBar{3, []Category{firstCategory}}
      
func main() {
    fmt.Println(p)
}

This outputs:
{3 [{Category1 [link one link two]}]}
and will fill:

           <div class="span2">
             <div class="well sidebar-nav">
             <ul class="nav nav-list">
              <li class="nav-header">Sidebar</li>
              <li class="active"><a href="#">Link</a></li>
              <li><a href="#">Link</a></li>
              <li><a href="#">Link</a></li>
              <li><a href="#">Link</a></li>
              <li class="nav-header">Sidebar</li>
              <li><a href="#">Link</a></li>
              <li><a href="#">Link</a></li>
              <li><a href="#">Link</a></li>
              <li><a href="#">Link</a></li>
              <li><a href="#">Link</a></li>
              <li><a href="#">Link</a></li>
              <li class="nav-header">Sidebar</li>
              <li><a href="#">Link</a></li>
              <li><a href="#">Link</a></li>
              <li><a href="#">Link</a></li>
            </ul>
          </div>
        </div>
