Your working environment and MDB version information

MDB PRO 4.5.9, Windows, any browser

In 4.5.8 this was not an issue. In 4.5.9 there is a new '_onMutationObserverChange' and it is my assumption this new function is the problem.

Version 4.5.8 Performance

Version 4.5.9 Performance

My script: function getMakesModels(id) { $.ajax({ type: 'GET', url: uri + "/getmakemodels/" + id, contentType: "application/json; charset=utf-8", dataType: "json", success: function (data) { document.getElementById('idxmodels').options.length = 0; $('#idxmodels').append(Choose a Model); $.each(data, function (i, item) { $('#idxmodels').append(${item}); }); $('.mdb-select').material_select('destroy'); $('.mdb-select').material_select(); }, failure: function (response) { alert(response.d); }, error: function (response) { alert(response.d); } }); }

Hi, indeed there is a nasty bug in our code. It's caused by MutationObservers which are not disconnected on the Material Select re-render. It has been fixed already and will be available in the nearest release. For now, you just need to get rid of the mentioned method and manually rebuild/re-minify the package. Sorry for inconveniences
