I have programmatically added #state into fields in a paragraph works fine for existing fields in a form. But on clicking ad more button on paragraph to add more fields the hidden fields show up. i tries this Patch → but it didnt work for me.
I have used this hook to alter the field to ass #state.
function mymodule_field_widget_entity_reference_paragraphs_form_alter(&$element, &$form_state, $context) {
$element['subform']['field_title']['#states'] = [
'invisible' => [
'#edit-parent-field-0-subform-parent-field-content-'.$element['#delta'].'-subform-target-field-wrapper select' => ['value' => 'value']
]
];
}
Closed: works as designed

I am trying to use a node field value to control the visibility of a paragraph form field.
This works on initial node form load, but the #state does not persist when the "add more" paragraph form is submitted.
I believe this is happening with the paragraph subform rebuild.
The #state does apply again if I change the field that controls the paragraphs field visibility after the new paragraph forms have rendered.
