Hi, friends in this post I show you how to make Ajax & jQuery cascading DropDownList using JSON. The subordinate select box will be a needed functionality if there is a dependency between options of the select box lists. Subordinate drop-down list box when we have select in parent select box then it will allow to refresh child select box data without a refresh of the web page. In this post, we have used JSON to store the data for fill parent and child select box and in that file, we have to give the link between parent data with child. We will use Ajax jQuery for fetch data from JSON and filled parent select box.
