+
+Sometimes one needs to nest collection loops, for example when implementing a master-detail page.
+
+The Antlers parser can't handle this form:
+```
+{{ collection from="blog" }}
+
+ {{ collection from="stuff" }}
+ {{ title }}
+ {{ /collection }}
+
+{{ /collection }}
+```
+
+But this works :
+```
+{{ collection:blog }}
+
+ {{ collection from="stuff" }}
+ {{ title }}
+ {{ /collection }}
+
+{{ /collection:blog }}
+```
+
+And so does this one:
+```
+{{ collection from="blog|events" }}
+
+ {{ partial:stuff_blog }} {{# contains the inner loop code #}}
+
+{{ /collection }}
+```
