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. [00:04:23](https://www.youtube.com/watch?v=3j4xPQC4apI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h04m23s) Either the one or the other of these options should be used. 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.<<<<<<<<<<

### Adding IDs

We need to add the IDs so we can come here(Fields) and I want to have Name, it's just 199. [00:05:04](https://www.youtube.com/watch?v=3j4xPQC4apI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h05m04s) I add 199 and a comma and then let's add something else. Let's add Website 280. Let's do an Email as well and it's 100. We have that in place.
IDs need to be added which we find in Fields. It should have 'Name', it is just '199'. [00:05:04](https://www.youtube.com/watch?v=3j4xPQC4apI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h05m04s) Add 199 and a comma and then add something else.A Website '280', an Email '100'. We have that in place.
### Adding A Description, Maximum, Filter, Showon
[00:05:33](https://www.youtube.com/watch?v=3j4xPQC4apI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h05m33s)
We can add a description. We can add a maximum, a filter, a showon. I'm just going to leave this. The validation of these fields, I think that is an area that I haven't looked into. But if I'm correct and also the reason why they moved away from Repeatable Fields, is that every field is validated on its own merit. For example, [00:06:05](https://www.youtube.com/watch?v=3j4xPQC4apI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h06m05s) the Name field, if you create a Name field, you're saying I want this to be a string and it has this filter string value. Since this is part of the XML it will be validated on this. I can be mistaken. I haven't looked at the code. That's what I anticipate it will do. In most cases I would say anticipate that it doesn't and try and do some custom scripting. I'm not going to illustrate that now. [00:06:44](https://www.youtube.com/watch?v=3j4xPQC4apI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h06m44s) You need to know a little bit more about JCB which there are tons of the tutorials to show you how to do custom scripting all around it a component and even to do custom scripting anywhere and any area of the component through the custom code area implementation. I'm going to talk more about that. Make sure it got all the spelling right. [00:07:15](https://www.youtube.com/watch?v=3j4xPQC4apI&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h07m15s) I'm going to save this, just give it a Name: Options (test), so I can see it. 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.
Then add a Description, a Maximum, a Filter and a Showon. The validation of these fields, that is an area that I have not looked into. Perhaps they moved away from Repeatable Fields because every field is validated on its own merit.
