There are lots of types of dragging that can happen on websites. While they are all click (or tap), hold down, move, and let go, they are all quite a bit different. For instance:
Drag files/folders onto the browser window and drop them. The likely use case there is uploading.
Drag an element on the screen to another (valid) area of the screen. The likely use case is dragging cards from one column to another
Drag the position of an element. The likely use case is dividers between different areas.

WordPress.com is easily the fastest way to spin up a great-looking WordPress site. Not to mention performant and secure, as your site will be hosted on the great WordPress cloud, and they make those things their concern, not yours. You might think you’d have to give up a lot of control and customizability when you use a fully hosted and managed WordPress service (as opposed to hosting yourself), but that’s actually not true. If you’re on the Business Plan or higher, you can install plugins, SFTP into the server, and even have direct database access like any other host.
