+Compact Inline
+==============
+
+
+By default Django admin interface provides two types of inlines to edit models on the same page as a
+related model – ``StackedInline`` and ``TabularInline``. ``StackedInline`` is mostly used when there are
+not so many objects. If number of models is rather big, ``TabularInline`` can help you. Unfortunately when
+related model has a lot of fields it may be not convenient to interact with them.
+To solve this problem JET has a ``CompactInline`` class built-in.

+
+
+Usage
+-----
+
+``CompactInline`` works exactly like Django built-in inlines, you need just
+to inherit ``jet.admin.CompactInline`` inline class. That's all.
+
+.. code:: python
+
+    from django.contrib import admin
+    from people.models import County, State, City
+    from jet.admin import CompactInline
+
+
+    class StateCountiesInline(admin.TabularInline):
+        model = County
+        extra = 1
+        show_change_link = True
+
+
+    class StateCitiesInline(CompactInline):
+        model = City
+        extra = 1
+        show_change_link = True
+
+
+    class StateAdmin(admin.ModelAdmin):
+        inlines = (StateCountiesInline, StateCitiesInline)
