# Conditional subnav display with Taxonomy

I have a tree like this:

About Us
- Alpha
- Beta
- Delta
* Three Sub 1
* Three Sub 2
Careers
- Full time


When the current page is 'Beta', since 'Beta' does not have any child entries and is at the second level of navigation, I want to hide my navigation breadcrumbs.

I have the breadcrumbs displaying fine, but how would I use a condition to check that a node is both at a certain level, and also has no children?

{exp:taxonomy:get_node tree_id="1" entry_id="{entry_id}"}
