In this example, we will explain to you how to drag and drop jquery example with the database. let's start how to create drag and drop jquery example using the jquery UI library.

We are using droppable, draggable and ajax in this example. first, we will connect the MySQL and we divided into two part left and right help through bootstrap. here this example in left known as "All List Country" and right known as "Selected Country".

We have taken the status field in the database. its value is a 0 and 1. The 0 status data are displaying into the left column and 1 status data are displaying into the right column. when left column country row drag and drop in the right column then will call the ajax that time it's row data status will be updated into the database. Like that it will be with the right column.

So you can see our example source code.
