This formsource(Optional) - it reads as follows: 'You can add a path to an XML file containing the fields'. So a custom XML file can be added to your component. How to add custom files to component, is a whole another topic. It is also possible within the Joomla Component to add files and folders, etc. That means this specific source can still be used but you do not need to. If you use the fields option then you need to remove the source option.

Currently, the fields are set to mandatory. By going to the field types it can be changed to be optional and then you can select other fields or formsource. The compiler will, in any case, detects a formsource will behave correctly.

Since this is part of the XML it will be validated on this. I have not looked at the code. That is what I suppose it will do. In most cases, I suppose that it does not and try and do some custom scripting but I am not going to illustrate that now.

This Data Type I would make TEXT. The default means that JCB (the Store method) already will detect that this is a Subform and will add the needed [00:07:39](https://www.youtube.com/watch?v=3j4xPQC4apI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h07m39s) PHP in storing the file and in loading the file into the form again. So that takes care of that. So you don't need to say Json, it will on its own by its default do the correct implementation. In the Data Type so you need to make sure either to click TEXT or MEDIUMTEXT depending on what this value is going to be. Anyway, I think for 50 text is quite enough. Save and close.

Let's see we got that field. I'm going to add it to any admin view for now. I'm going to add it to Look View, that we can see it in action. The look view is part of the Demo component. I'm just going to dump it here. Let's see the above tab, full width, details, description. I think let's just add it there. Details also full width, make it the 2nd, and I say [00:08:49](https://www.youtube.com/watch?v=3j4xPQC4apI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h08m49s) Options(test). Save and close. We've added it to a view. Now I'm just going to compile this component which the view belongs to. Which at this stage it is demo and install it. Now let's go open that Demo component, and open Looks. And here we go, enter name here, enter website address, enter email. We click the green plus button [00:09:26](https://www.youtube.com/watch?v=3j4xPQC4apI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h09m26s) and our values are there. Let's just save one. Children. We can do I think that's the only one. (see video)Let's do that and by entering those values I'm just going to grab joomlamount.com up here, [00:09:55](https://www.youtube.com/watch?v=3j4xPQC4apI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h09m55s) paste it in there a few times. I'm going to put Joomla@vdm.io in Email. To get sort of a feel for it. Save. It saved the values, it loaded it back, it's done all of that. 'Hi, there' then save and close. [00:10:45](https://www.youtube.com/watch?v=3j4xPQC4apI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h10m45s) If we open it again, it shows it up again. We can shuffle it, put number four on top. Save and close. Open again and so it is loading it also correctly. That's a quick demonstration Marco I hope this helps [00:11:09](https://www.youtube.com/watch?v=3j4xPQC4apI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h11m09s) and getting you able to use subforms with JCB. It's as easy as that.
Add this field Options(test) to any admin view, for instance, to Look View, to see it in action. The Look view is part of the Demo component. I am going to dump it here. Look at the above tab, full width, details, description. Let's just add it to details, full width, make it 2nd, and say Options(test).
