+~~~~~~~~~~~~~
+
+    Target a ``<solid-form-search>`` used to provide several options for the user to sort current list of resource.
+
+    The ``fields`` attribute of ``<solid-form-search>`` must at least contain ``field``. 
+    ``Field`` attribute contains the fields of the resource to be offered to the user for sorting the data.
+
+    ``Order`` attribute allows you to propose 2 sorting orders: ascending (``asc`) and descending (``desc``). 
+    By default, the order is ascending.
+
+    The ``<solid-display>`` cannot combine ``order-asc`` or ``order-desc`` attribute AND ``sorted-by`` attribute.
+
+    example:
+
+    .. code:: html
+
+        <solid-form-search
+            id="my-sorter"
+            fields="field, order"
+            enum-field="username, email"
+            enum-order="ascending order = asc, descending order = desc"
+        ></solid-form-search>
