title: Can I limit jstree check box to only parents with children?
body: <p>I'm wondering if I can provide a checkbox only on the parent that has children with no children. </p>
  
  <p>Something like this. I can select a single child, or the child's immediate parent that would select all the children. </p>
  
  <pre><code>parent01
      parent02
          parent03[]
              child01[]
              child02[]
              child03[]
                  parent04[]
                      child04[]
          parent05[]
              child05[]
      parent06
          parent07
              parent08[]
                  child06[]
                  child07[]
  </code></pre>
