Need help finding an IF command

[eNforce]

I took the breadcrumb navigation out of the navbar and created a new box for it, what IF statement can I use to hide the box until you enter a forum or thread?

You can see the empty box that needs to be hidden on my site under the tabs

edit: i kind of figured it out... sort of

Edit: yeah I did figure it out, wrapped my custom code with the <if condition="is_array($navbits)"> </if>
