$('select[name=problems]').dropdown('destroy').dropdown({     mincharacters: 3,     saveremotedata: false,     apisettings: {         on: 'change',         url: '/ajax/contest.getproblemquery/',         method: 'post',         data: {             argv: {                 page: 0,                 limit: 1000             }         },         beforesend: function (settings) {             settings.data.argv.q = settings.urldata.query;             return settings;         },         beforexhr: function (xhr) {             console.log('xhr');             console.log(xhr);             xhr.setrequestheader('x-requested-with', 'xmlhttprequest');             xhr.setrequestheader('x-csrftoken', $.cookie('csrftoken'));             return xhr;         },         onresponse: function (response) {             console.log('onresp');             if ( response != 'f' && response.length != 0 ) {                 var list = {results: [], success: true};                 ( var = 0; < response.items.length; ++i ) {                     list.results.push({                         value: response.items[i][0],                         name: response.items[i][1] + ' - ' + response.items[i][2],                         text: response.items[i][1] + ' - ' + response.items[i][2]                     });                 }                 return list;             }             else                 return {success: false};         },         successtest: function (response) {             return response.success || false;         },         oncomplete: function (response, element, xhr) {             // called after xhr complete         },         onsuccess: function (response, element) {             console.log('suc');             console.log(response);             // valid response , response.success = true         },         onfailure: function (response, element) {             console.log('fail');         },         onerror: function (errormessage, element, xhr) {             // invalid response         },         onabort: function (errormessage, element, xhr) {             // navigated new page, cors issue, or user canceled request         }     } });

my problems:

  1. it not send request until put "{query}" in side url.
  2. when sends request , receives data, data stores in browser session storage. set 'saveremotedata' false after each request checked storage , found new record on that.
  3. after receives response change format said in sematic-ui.com/modules/dropdown.html#/examples [remote content] not show me items in dropdown section.

when sends request , receives data, data stores in browser session storage. set 'saveremotedata' false after each request checked storage , found new record on that.

probably it's api's bug. i've had same issue, , couldn't find solving in internet. wrote own kludge.

html:

<div id="my_dropdown" class="ui multiple search selection dropdown select-city">     <input type="hidden" name="city"> <i class="dropdown icon"></i>     <div class="default text">select city</div>     <div class="menu"></div> </div>

and js inside dropdown({}):

beforesend: function(settings) {     /**      * mincharacters option doesn't work form me dropdown,      * i'm checking length manually , clear search result in dom      * , reject request if search string short      */      if ($("#my_dropdown").find("input.search").val().length < 3) {          $("#my_dropdown").find(".menu.transition.visible").html("");          return false;      }      /**       * here i'm manually clearing cache in localstorage       */      if (typeof(storage) !== "undefined") {          var sstorage = window.sessionstorage;          //console.log(sstorage.getitem("/my/request/url/"));          sstorage.removeitem("/my/request/url/");      }      /**       * standard actions      */      settings.data.str = $("#my_dropdown").find("input.search").val();      console.log(settings.data);      return settings; }

looks bit ugly, works me.
