Usage

30 |

1. Include jQuery and the plugin.

31 | 32 |
<script src="path/to/jquery.js"></script> 
 33 | <script src="path/to/jquery.nice-select.js"></script>
34 | 35 |

2. Include the plugin styles, either the compiled CSS...

36 | 37 |
<link rel="stylesheet" href="path/to/nice-select.css">
38 | 39 |

...or, ideally, import the SASS source (if you use SASS) in your main stylesheet for easier customization.

40 | 41 |
@import 'nice-select'; // Or 'nice-select-prefixed'. See 'Notes' section.
42 | 43 |

3. Finally, initialize the plugin.

44 | 45 |
$(document).ready(function() {
 46 |   $('select').niceSelect();
 47 | });
48 | 49 |

All done. That will turn this:

50 | 51 |
52 | 58 |
59 | 60 |

...into this:

61 | 62 |
63 | 69 |
70 | 71 |

There are no settings (a native select doesn't have settings), although there are a couple of special features, documented below.

72 | 73 |

Display text

74 |

You can specify an alternate text for each option, which will be displayed on the dropdown when that option is selected.

75 | 76 |

Add a data-display attribute to the desired options. For example:

77 | 78 |
<select>
 79 |   <option data-display="Select">Nothing</option>
 80 |   <option value="1">Some option</option>
 81 |   <option value="2">Another option</option>
 82 |   <option value="3" disabled>A disabled option</option>
 83 |   <option value="4">Potato</option>
 84 | </select>
85 | 86 |
87 | 94 |
95 | 96 |

Custom classes

97 | 98 |

Every class you assign to a select element will be copied to the generated dropdown. That way you can customize different versions of it to your needs just by adding new CSS.

99 | 100 |

These are some examples included in the plugin stylesheet:

101 | 102 |
103 | 104 | 111 |
112 | 113 |
114 | 115 | 122 |
123 | 124 |
125 | 126 | 133 |
134 | 135 |

Methods

136 | 137 |

update

138 | 139 |

Updates the custom dropdown to reflect any changes made to the original select element.

140 | 141 |
$('select').niceSelect('update');
142 | 143 |

destroy

144 | 145 |

Removes the custom dropdown and unbinds all its events.

146 | 147 |
$('select').niceSelect('destroy');
148 | 149 |
