I have a site structure like this. --\> denote children

Main Page  
–\>scicomp  
----\>student\_projects  
----\>instruments  
------\>gcms  
------\>ftir  
------\>sem  
–\>other areas

h3. Scientific Computing  
\<r:find url="/scicomp/"\>  
\<r:children:each order=“asc”\>

- \<r:link /\>  
\<r:if\_url matches="/instrumentation/"\>  
\<r:children:each order=“asc”\>  
\*\* \<r:link /\>  
\</r:children:each\>  
\</r:if\_url\>  
\</r:children:each\>  
\</r:find\>

I want to have a sidebar menu that when the instruments section in  
being viewed the children of the instruments page are listed. When  
that section is not being viewed are hidden. I had though that the  
above would do this but instead it always should the sub-menu. Any  
thoughts.

FYI I love that radiant does all the right stuff to be DB agnostic.

That’s because the \<r:if\_url /\> tag is being evaluated within the  
context of the child URL. You need to bump it back out so that it  
references the current page’s url. Try this instead:

\<r:page:if\_url matches=“/instrumentation/”\>  
…  
\<r:page:if\_url\>

The \<r:page /\> tag changes the context back to the current page.

Thanks. I keep forget the objecty nature of the tag syntax. It takes  
a little getting used to but it is nice.

Most of the time I think it’s what you would expect, but occasionally it  
catches you by surprise. 🙂
