jsfiddle

one approach track expanded accordion e.g:

var currentactive; // track current active accordion. 

and close when 1 expanded,

var toggleaccordionstate = function(accordion) {       accordion.classlist.toggle("active");       accordion.nextelementsibling.classlist.toggle("show"); };  (i = 0; < acc.length; i++) {     acc[i].onclick = function(){         if(currentactive) {                 toggleaccordionstate(currentactive);  //close current accordion.         }         toggleaccordionstate(this);         currentactive = this;     // save current open accordion      }
