ASP.NET MVC ComboBox - Multiple Rows and Columns

Four columns:
  Three columns:
  Two columns:
The items of the ComboBox can be arranged on multiple columns.
This can easily be achieved using a small CSS trick:

.ob_iCboICBC li { float: left; width: 125px; }

The ComboBox will arrange its items on as many columns as possible, taking the width of the drop down menu and the width of the individual items into account.

When arranging the items in multiple columns, your end users will still benefit from the other features of the ComboBox: autocomplete, load on demand, virtual scrolling, filtering, etc.
