Dynamically add content in the multiselect dropdown in jquery

Question

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(...)

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'); }); $("#remove").click(function() { $("#test001 option:last").remove(); $("#test001").multiselect('refresh'); });
