       Note that a blank line is *required* after every ``code-block`` directive.
 
+- **Collapsible section**: To add a collapsible section, use the ``collapse`` directive:

+  .. code-block:: rst
+
+      .. collapse:: Details

+          Something small enough to escape casual notice.

+  The ``:open:`` flag can be used to have the section open by default.
+
+  .. code-block:: rst
+
+      .. collapse:: Open
+          :open:
+
+          This section is open by default.
+
+  .. collapse:: Open
+      :open:
+
+      This section is open by default.
+
+  .. note::
+
+      - The ``:open:`` flag must immediately follow the ``collapse`` directive without a blank line between them.
+      - A blank line is *required* after every ``collapse`` directive.
+
+- **Tabs**: To group content into tabs, use the ``tabs`` directive. The tabs directive defines a tab set.
+  Basic tabs are added using the ``tab`` directive (without s), which takes the tab’s label as an argument:
+
+  .. code-block:: rst
+
+      .. tabs::
+
+          .. tab:: Apples
+
+              Apples are green, or sometimes red.
+
+          .. tab:: Pears
+
+              Pears are green.
+
+          .. tab:: Oranges
+
+              Oranges are orange.
+
+  This will appear as
+
+  .. tabs::
+
+      .. tab:: Apples
+
+          Apples are green, or sometimes red.
+
+      .. tab:: Pears
+
+          Pears are green.
+
+      .. tab:: Oranges
+
+          Oranges are orange.
+
+  Tabs can also be nested inside one another:
+
+  .. code-block:: rst
+
+      .. tabs::
+
+          .. tab:: Stars
+
+              .. tabs::
+
+                  .. tab:: The Sun
+
+                      The closest star to us.
+
+                  .. tab:: Proxima Centauri
+
+                      The second closest star to us.
+
+                  .. tab:: Polaris
+
+                      The North Star.
+
+          .. tab:: Moons
+

+                  .. tab:: The Moon

+
+              .. tab:: Proxima Centauri
+
+                  The second closest star to us.
+
+              .. tab:: Polaris
+
+                  The North Star.
+

+              .. tab:: Titan
+

+
+  .. note::
+
+      - A blank line is *required* after every ``tabs`` directive.
+      - The contents of each tab can be displayed by clicking on the tab that you wish to show.
+        Clicking again on the tab that is currently open will hide its content, leaving only the tab set labels visible.
