I have implemented the selectize framework for my dropdown list in asp.net mvc4 and successfully modified the CSS for all form fields bound to asp.net mvc4's validation engine.
However, I am facing an issue with creating a border around the dropdownlist for selectize. Although it is connected to the validation process (errors appear in the summary if nothing is selected), I would like to add a red border around it as well.
Take a look at this jsFiddle example I stumbled upon: http://jsfiddle.net/249Wz/4/
Here's the CSS code I intend to use:
.input-validation-error {
border: 1px solid #f00;
background-color: #fee;
}
