How to dynamically modify <select> in materi

Question

I just started using the materialize css framework. Now, materialize converts any select tag into a collection of ul and li elements. Before, using JQuery, I was able to do this:

var $selectDropdown = $("#dropdownid");
$selectDropdown.empty();
$selectDropdown.html(' ');
var value = "some value";
$selectDropdown .append($("<option></option>").attr("value",value).text(value));

My html is just a sample select tag:

Before, this was working. Now it fails. What would be an alternative for repopulating this dropdown dynamically using javascript?

Answer 1

$(document).ready(function() {

  // initialize
  $('select').material_select();


  $("#myButton").click(function() {

    // clear contents
    var $selectDropdown = 
      $("#dropdownid")
        .empty()
        .html(' ');

    // add new value
    var value = "some value";
    $selectDropdown.append(
      $("<option></option>")
        .attr("value",value)
        .text(value)
    );

    // trigger event
    $selectDropdown.trigger('contentChanged');
  });


  $('select').on('contentChanged', function() {
    // re-initialize (update)
    $(this).material_select();
  });

});
