 Is that possible?

+
+The site I'm trying to set up right now (not really a wiki - no public editing) is divided into topics.  Topics are pages that have `\[[!meta link="/topic"]]`.  Topic pages contain an index of their subpages (done with `\[[!inline]]`); the subpages are the real content.  I want a map in the sidebar that lists:
+
+ * all of the topics;
+ * all of the first-level subpages of the *current topic only*.
+
+That is, if the current page is "Topic A" or "Topic A/Page 1", then the map should look like
+
+    Topic A
+        Page 1
+        Page 2
+        Page 3
+    Topic B
+    Topic C
+
+but if the current page is "Topic B" or one of its subpages, then the map should look like
+
+    Topic A
+    Topic B
+        Page 1
+        Page 2
+        Page 3
+    Topic C
+
+On the top-level index page, or on any other page that is neither a topic nor a subpage of a topic, the map should list only the topics.
+
+Is there any way to do that?  I don't mind mucking around with `\[[!meta]]` on every page if that's what it takes.
