+
+# Usage
+
+The dropdown container is used to display elements horizontally in a responsive way. If the elements don't fit in
+the available width, they are displayed vertically in a dropdown. Some of the common applications in Superset are:
+
+- Display chart filters in the CRUD views
+- Horizontally display native filters in a dashboard
+
+# Variations
+
+The component accepts any React element which ensures a high level of variability in Superset.
+
+To check the component in detail and its interactions, check the [DropdownContainer](/story/dropdowncontainer--component) page.
