How to implement a multi-column Dropdown list? See attached image for more clarity

Hi,

This post is more of a question than an article.

I want to implement a multi-column drop down box where in I should be able to filter the results appearing below as I type along with auto-complete feature. A sample implementation of what I want can be seen in the below image.

I want to implement a similar Drop down list using C#. Can someone please help me out with it? I have referred to THIS LINK which pretty much shows exactly what I’m expecting but it is being done in LightSwitch. I’m not really aware of LightSwitch but still I’m trying. Meanwhile, if someone can guide me in creating similar functionality in C#, ASP.NET, it would be great! 🙂

Thanks a lot!!
