[2.0.0-alpha3] Form builder: Simpler sources selector (2/3) + make it nestable

$wrapper_id = 'ui-patterns-prop-item-' . $prop_id; > ADD random if many form

Started.

UUID like in image effects in an image style?

Make sure the slots' source selector works with Layout Builder, it has a broken look with ui_suite_bootstrap. Maybe the simplification will help.

modules/ui_patterns_field_formatters/src/Plugin/UiPatterns/Source/FieldFormatterFormBase.php also needs $wrapper_id = Html::getUniqueId('field-formatter-settings-ajax');

While comparing the HTML of a native field_multiple_value_form on a content type. The "remove" button is in the third "td" while In UI Patterns it is in the second. So maybe there is some malformed HTML too.

Also I am not sure if field_multiple_value_form is appropriate to use outside of the field API. Maybe there are field API related mechanism that ensures it works properly but are missing in the configuration forms.

When using a component without props, I get the warning:

Warning: Trying to access array offset on null in Drupal\ui_patterns\Element\ComponentPropsForm::buildForm() (line 62 of modules/custom/ui_patterns/src/Element/ComponentPropsForm.php).

However:

• no Delete button and it looks complicated to add: ✨ Add a delete button Active
• this form element expects the first line to be already initialized. This first line will be duplicated every time we click on “Add” button. However, us, we start with an empty form, with no source in the slot

This task is strategic because following tasks depend on it:

• "Formatter" source (from ui_patterns_field_formatters) and by the upcoming ✨ [2.0.0-alpha3] Add block source (for slots) Fixed need the forms to be nestable (with working random non-duplicated wrapper IDs)
• ✨ [2.0.0-alpha3] Make Form Builder and/or Source plugins forms extendable Active
• ✨ [2.0.0-alpha3] Add allow_variant_expose source plugin Active

Once done, restest FieldFormatter source from ui_pattterns_field_formatters.

Hello,
i have worked on this issue, focusing on how to nest patterns.
the new code also removes the key "component_form" from the form objects...
please review, thank you :)
