3 State CSS Toggle Switch

Question

I have been looking around for a 3 state toggle switch but haven't had much luck.

Basically I need a switch that has the states: | ON | N/A | OFF |

The slider by default starts in the middle, and once the user slides to left or right, they can't go back to the N/A (not answered) state.

Anyone have any idea on how to handle this?

Answer 1

Try something like this:

.switch-toggle {
  width: 10em;
}

.switch-toggle label:not(.disabled) {
  cursor: pointer;
}

<link href="https://cdn.jsdelivr.net/css-toggle-switch/latest/toggle-switch.css" rel="stylesheet" />

<div class="switch-toggle switch-3 switch-candy">
  <input id="on" name="state-d" type="radio" checked="" />
  <label for="on" onclick="">ON</label>

  <input id="na" name="state-d" type="radio" disabled checked="checked" />
  <label for="na" class="disabled" onclick="">&nbsp;</label>

  <input id="off" name="state-d" type="radio" />
  <label for="off" onclick="">OFF</label>

  <a></a>
</div>

This will start with N/A as the default option (via checked="checked"), but make it unselectable later (by using disabled)

.switch-toggle {
   float: left;
   background: #242729;
}
.switch-toggle input {
  position: absolute;
  opacity: 0;
}
.switch-toggle input + label {
  padding: 7px;
  float:left;
  color: #fff;
  cursor: pointer;
}
.switch-toggle input:checked + label {
  background: green;
}

 <div class="switch-toggle switch-3 switch-candy">

  <input id="on" name="state-d" type="radio" checked="" />
  <label for="on" onclick="">ON</label>

  <input id="na" name="state-d" type="radio" checked="checked" />
  <label for="na" class="disabled" onclick="">N/A</label>

  <input id="off" name="state-d" type="radio" />
  <label for="off" onclick="">OFF</label>

</div>

As a jQuery plugin

function filterme(value) {
  value = parseInt(value, 10); // Convert to an integer
  if (value === 1) {
    $('#RangeFilter').removeClass('rangeAll', 'rangePassive').addClass('rangeActive');
    $('span').text('Active');
  } else if (value === 2) {
    $('#RangeFilter').removeClass('rangeActive', 'rangePassive').addClass('rangeAll');
    $('span').text('All');
  } else if (value === 3) {
    $('#RangeFilter').removeClass('rangeAll', 'rangeActive').addClass('rangePassive');
    $('span').text('Passive');
  }
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p class="range-field" style=" width:60px">
  <input type="range" id="RangeFilter" name="points" onchange="filterme(this.value);" min="1" class="rangeAll" max="3" value="2">
</p>
<span>All</span>

(function($) {
  $.fn.removeClasses = function(classes) {
    return this.removeClass(classes.join(' '));
  };
  $.fn.switchify = function(config) {
    config = config || {};
    var prefix   =           config.prefix   || 'range-';
    var onCls    = prefix + (config.onCls    || 'on'   );
    var offCls   = prefix + (config.offCls   || 'off'  );
    var unsetCls = prefix + (config.unsetCls || 'unset');
    var $self = this;
    return this.on('change', function(e) {
      var value = parseInt(this.value, 10);
      switch (value) {
        case 1  :  return $self.removeClasses([unsetCls, offCls]).addClass(onCls);
        case 2  :  return $self.removeClasses([onCls, offCls]).addClass(unsetCls);
        case 3  :  return $self.removeClasses([onCls, unsetCls]).addClass(offCls);
        default :  return $self;
      }
    });
  };
})(jQuery);

$('#range-filter').switchify({
   onCls    : 'active',
   offCls   : 'passive',
   unsetCls : 'all'
}).on('change', function(e) {
  var $self = $(this);
  if      ($self.hasClass('range-active'))  $('span').text('Active');
  else if ($self.hasClass('range-passive')) $('span').text('Passive');
  else if ($self.hasClass('range-all'))     $('span').text('All');
  else                                      $('span').text('Error!');
});

.range-field { width: 60px; }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p class="range-field">
  <input type="range" id="range-filter" name="points" min="1" class="rangeAll" max="3" value="2">
</p>
<span>All</span>
