When loading the mdb-select site, the styles are loaded not immediately, but with a delay. The select itself appears with a second delay. 
Tried to do parallel script loading and asynchronous. Nothing helps. Help me fix it.

$(document).ready(function(){    
   $(\"select\").addClass(\"mdb-select\"); 
   $(\'.mdb-select\').material_select();
}); 
refresher_global_callback=function($el){$el.material_select();}
