[6.x] Add extra sections with fields to existing fieldtypes

[nopticon]

After reading https://statamic.dev/fieldtypes/build-a-fieldtype#adding-config-fields-to-existing-fieldtypes I noticed that extra sections are not added to fieldtype config.

use Statamic\Fieldtypes\Text;

Text::appendConfigFields([
    [
        'display' => __('Extra section'),
        'fields' => [
            'more_options' => [
                'display' => __('Options'),
                'instructions' => __('Instructions for this field'),
                'type' => 'array',
            ],
        ],
    ],
]);

Before this fix, it shows like this:

After fixing this issue, it shows fields inside the new section:

After adding appendConfigFields to a ServiceProvider, it can be tested on any blueprint at /cp/collections/{collection}/blueprints/{blueprint}/edit

Not sure this is the right way to check, as replicators and bards both have fields so this check would mark them both as sections.

Hi @ryanmitchell Are you referring to replicators and bard fields that you want to add with appendConfigFields method? Something like this:

This check does validate fields key on the first level of the array generated by

cms/src/Fields/Fieldtype.php

Line 293 in 80f7049

protected function extraConfigFieldItems(): array

but it's not recursive for other fields keys, so I haven't seen the behavior that you mentioned. This PR does not affect other existing fields beside the ones that you define calling appendConfigField or appendConfigFields method.

I did a lot of tests in my dev site and all fields seems to be working fine, if you see something weird is happening please let me know. Thanks for your review!

This is how it looks for my custom test calling Text::appendConfigFields():
