Select2 example is not working

Question

I am trying to use Select2.js plugin . I have created a fiddle of the simplest example of select2 but i can't figure out why this is not working ?

you can see in the fiddle that selection of items in selectlist and allow clear is not working.

Can anybody please help me, what i am doing wrong here ?

Answer 1

You should use options value to enable selection

and

you should use an empty option for showing placeholder and allowClear option.

Here is the working fiddle :

Main code copied from the link:

HTML:

<select id="e2" style="width:200px;">
  <option value=""><option>
  <option value="1">Mustard</option>
  <option value="2">Ketchup</option>
  <option value="3">Relish</option>
</select>

JavaScript:

$("#e2").select2({
  placeholder: "Select a State",
  allowClear: true
});

Answer 2

旧版本要求您在下拉列表中添加“select2”类。
