I want to change materialize select box value by jquery.
I am using $(\'#myselect\').val(\'1\'); on onchange event of other select box but
This answer might be late but it might help someone else.
On Ready add the line below
$(document).ready(function () {
$('select').formSelect();
});
Each time you change an option within your Select add the line below
$("#select1").change(function() {
$('#myselect').val('1');
$('select').formSelect();
});
This is what worked for me, hope it helps.
