jQuery Question

Dynamically add content in the multiselect dropdown in jquery

I have some doubt on multiple select in dropdown with checkbox. i want to dynamically add the content in drop down whenever i upload a image in jquery.How to refresh dropdown with new data?

$('#listImage').multiselect({});


once i get the new data i tried to refresh the multiselect but that throws error.

$("#widgetSettingsForm select[multiple]").multiselect('rebuild');


Uncaught Error: no such method 'rebuild' for multiselect widget instance(...)

Answer

Use refresh instead of rebuild : http://jsfiddle.net/o7xf9awv/1/

$("#test001").multiselect('refresh');

$("#test001").multiselect({
  header: false,
  noneSelectedText: "Select"
});
var count = 2;
$("#add").click(function() {
  $("#test001").append('<option value="option5">Option ' + ++count + '</option>');
  $("#test001").multiselect('refresh');
});
