+Lastly, the search value can be a *regular expression* to make things easier when dealing with complicated routes, sub-

+      profile_activator = Navigator::TagActivator.new search_value: /^profile.+/
+
+      navigation do
+        item "Dashboard", dashboard_path
+        li activator: profile_activator do
+          link "Profile", '#'
+
+          ul do
+            item "Addresses", profile_addresses_path
+            item "Emails", profile_emails_path
+          end
+        end
+      end
+
+      <!-- Result -->
+      <ul>
+        <li><a href="/dashboard">Dashboard</a></li>
+        <li class="active">
+          <a href="#">Profile</a>
+          <ul>
+            <li><a href="profile/addresses">Addresses</a></li>
+            <li><a href="profile/emails">Emails</a></li>
+          </ul>
+        </li>
+      </ul>
+
+Assuming either the `Addresses` or `Emails` menu item was clicked, the `Profile` menu item would be active due to the
+regular expression (i.e. `/^profile.+/`) matching one of the the `profile/*` paths.
