Need to add selects/dropdowns to a basic asp.net MVC site?

The classic jquery plugin for this is Chosen and its more up to date descendant, Select2 (What are the differences?)

I'd forgotten all about these until I needed them today.

To use Select2:

Add the nuget package for select2 (and jquery if you haven't already)

If it hasn't automatically added the select2.css and select2.js to your _layout.cshtml then do that manually. Like a primitive cave dweller.

For implementation patterns see:

• How to add dynamically populated selects/dropdowns to a basic asp.net MVC site?
• How to add multi-select dropdowns to a basic asp.net MVC site?

Here's some rough CSS I added to site.css, to make these fit in with Twitter Bootstrap a little better:

.select2-container {
    font-size: 1.2em;
}
.select2-container--default .select2-selection--single {
    border-radius: 0;
}

/* Select 2 styling hacks...*/
.select2-container--default .select2-selection--multiple {
	border: 1px solid #CCC;
	box-shadow: inset 0px 1px 1px rgba(0,0,0,0.075);
	width: 280px;
}
.select2-container--default.select2-container--focus .select2-selection--multiple {
	border-color: #66afe9;
	outline: 0;
	-webkit-box-shadow: inset 0 1px 1px rgba(0,0,0,.075), 0 0 8px rgba(102, 175, 233, .6);
	box-shadow: inset 0 1px 1px rgba(0,0,0,.075), 0 0 8px rgba(102, 175, 233, .6);
}

/* end select2 */
