+        * `beforeRender`: `function (container) {}` called before displaying the suggestions. You may manipulate suggestions DOM before it is displayed.
         * `tabDisabled`: Default `false`. Set to true to leave the cursor in the input field after the user tabs to select a suggestion.
         * `paramName`: Default `query`. The name of the request parameter that contains the query.
         * `transformResult`: `function(response, originalQuery) {}` called after the result of the query is ready. Converts the result into response.suggestions format.
