+ * changes and draws an additional submit button when JavaScript is disabled.
+ *
+ * The constructor takes a string for the component name and an array containing the select options, where the key is
+ * the value to be submitted and the value is the label that will be shown. You then should call setRequest in order
+ * to make sure the form is correctly populated when a request with a sort parameter is being made.
+ *
+ * Call setQuery in case you'll do not want to handle URL parameters manually, but to automatically apply the user's
+ * chosen sort rules on the given sortable query. This will also allow the SortBox to display the user the correct
+ * default sort rules if the given query provides already some sort rules.
