This is the JavaScript that we will be using. It has a nice progress bar and everything. This is the HTML that we will be using. It has a nice drag and drop and selecting area. You can give some information to the user as well as have them drop in the file right there. It works very well.

If you want to see the Version 3 option, simply click on Version 3 documentation. Scroll to the bottom where it says Upload. Then Select, there is Markup for the Select.

You could use this(see video), and then JavaScript. It looks very much the same except for a few changes. For the most part, it is generally the same kind of approach. You would be able to plug-in this if instead, you want to use UIkit 3, or any other library.

The URL is going to be dynamic as to whether it is going to be allowing multiple or single. This one allows what type of image or file you want to permit to be uploaded. The action is where the URL is.

You are able to upload the file without saving the item whenever this area is available. You can simply use a note to add this script to your page.

If somebody drops something here, it is going to be posted to the server. If the item has an ID, I passed the ID that it gets stored in the database immediately. <<<<<<<<<<

### Saved Or Not Saved - File is Added To The Item
[00:05:40](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h05m40s)
Even if you save it or don't save it, the file is added to that item. If it's a new item which means no ID, we will add a hidden field to the form. We return the actual value that must go to the database, and we put it in that hidden field. When you do save the item, it does store it in the correct place. That's the approach I'm going to demonstrate to you. Step-by-step with an existing component which I've found there and which is using. It is available in JCB.

### New - Import JCB Packages

You'll see there is a new Import JCB Packages. You could either click on Import JCB Packages or you can go to Joomla Components and click on Import Components. It's really the same thing. I'm going to go back to the Dashboard and click on Import JCB packages. There has been a release fix, I think it was been in a the previous release. If you click on Import JCB Packages it didn't give you [00:06:53](https://www.youtube.com/watch?v=UvzDyVQyHDI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h06m53s) this VDM Package tab. It only gave you Upload, Directory and URL. In fact it's a little broken. The best then go to Joomla Components and ensure to click on Import Components. Make sure that it gives you this VDM Packages tab.

It's the only part of the import of the components that already does validation on the package integrity. For each of these packages that are here, we do have a validation. Giving your example, Hello World is not here. If I was to select Hello World, click Get Package. It fetches it from GitHub.
