Hope you all are doing well.
I am developing a Meeting Room Reservation System in Visual Studio 2008.
In this I am trying to use Metro UI Drop down
I have added the Css and Javascript file
But I am getting error in JS due to following Error

Thanks In Advance

I am Getting this Error in JS
The JS error states that
$ === nullthis is unrelated to the HTML and a result of passing null as the argument tofunction($)the most likely cause for this error is that the script you are showing a picture of is included prior to including jQuery in the page
