Implement component params for fieldgroups

[rdeutz]

Summary of Changes

This is pretty much the same as #15915 but only for field groups.

Com_categories has a nice little feature which allows the component developer to place a form file on /administrator/components/com_foo/models/forms/category.xml which get loaded when editing a category.

This pr introduces the same functionality for com_fields. If a file is found on the location /administrator/components/com_foo/models/forms/fieldgroup/item.xml then this file get loaded when the entity com_foo.bar is edited.

You have to name the fields params

<?xml version="1.0" encoding="utf-8"?>
<form>
    <fields name="params">
        <fieldset name="basic">
            <field
                    name="display"
                    type="text"
                    default=""
            />
        </fieldset>
    </fields>
</form>

Testing Instructions

Put the xml in a component with custom fields support into
/administrator/components/com_foo/models/forms/fieldgroup/item.xml

Item is the section, check https://docs.joomla.org/J3.x:Adding_custom_fields/Implement_into_your_component for details

Expected result

You should see a new tab Options in your fieldgroup edit form

Documentation Changes Required

Would be nice to have that feature documented.

Needs the install SQL but seems fine to me. If this can get tested today and tomorrow don't see any reason not to merge.

[rdeutz]

grrr, adding the install sql, I was sure I have forgotten something but couldn't figure out what :-)

Looks good for me. Everything works

Should the update files not contain 3.8.0 as version number and end with a new line?

[rdeutz]

Ofc, they should :-)

I tried this on com_content and can't show the new field.

[nielsnuebel]

@infograf768 change item.xml to article.xml .

Got it and I do get a new Option tab when editing a fieldgroup. But what can be the use of other Options in the fieldgroup itself? Any example that makes sense?

I have tested this item ✅ successfully on 298ffab

Ready to go.

Think about a component where you have different fieldgroups, any of them should work a little bit different. With having the ability to add fields to the formgroup you can save the information how they should behave. Then you have to pick up the information in your overwrite/component and act accordingly.

Thanks all who have been worked on this :-)
