Hello, I am trying to build a website with Radiant CMS and the basic  
style of the site is a navigation bar at the top and content below, with  
a sidebar depending on the content. What I am trying to do is decide if  
I should put a sidebar or not using a boolean tag as follows  
\<r:unless\_url matches="^/$"\> but I want to put additional page checks in  
there, such as \<r:unless\_url matches="^/$" OR matches="^/gallery/$"\> .  
Is this possible and if so, what is the proper syntax. I have looked  
through the Radiant site and found nothing to help me.  
Thanks

What you want to do could be expressed with regular expressions:

\<r:unless\_url matches="^/(gallery/)?$"\>
