the option size is doesn't work?

[jerry-yuan]

No matter whether I use the $(...). bootstrapSwitch ({size:"small"}) or add data-size = "small" to the input, I can't achieve small space. By the way, I found that there are lots of bootstrap-switch-undefined in the class attribute of wrapper which contains the switch elements.

I have the same problem.
i use the CSS file and not the less file.

CSS and JS are v.3.3.4 on the demo site as in the repository, but the version on the site works!
bootstrap-switch.js
bootstrap-switch.css

function getClasses(options, id) {
    var state = options.state,
        size = options.size,
        disabled = options.disabled,
        readonly = options.readonly,
        indeterminate = options.indeterminate,
        inverse = options.inverse;

    return [state ? 'on' : 'off', size, disabled ? 'disabled' : undefined, readonly ? 'readonly' : undefined, indeterminate ? 'indeterminate' : undefined, inverse ? 'inverse' : undefined, id ? 'id-' + id : undefined].filter(function (v) {
      return v == null;
    });
  }

be revised as

function getClasses(options, id) {
    var state = options.state,
        size = options.size,
        disabled = options.disabled,
        readonly = options.readonly,
        indeterminate = options.indeterminate,
        inverse = options.inverse;

    return [state ? 'on' : 'off', size, disabled ? 'disabled' : undefined, readonly ? 'readonly' : undefined, indeterminate ? 'indeterminate' : undefined, inverse ? 'inverse' : undefined, id ? 'id-' + id : undefined].filter(function (v) {
      return v != null;
    });
  }

Returns the option of null:
return v == null;

So it's all undefined

@matusmark bootstrap-switch. Js is right

[insmod]

@Wong-Dy you are correct, please submit a pull-request because it works as intended just by changing that

FYI Fixed by #713

I had a try as this just, but it seems not to work
