Editing forms

Forms::update($key) returns a builder that diffs your definition against the persisted structure and saves the changes in a transaction — adding new groups and fields, renaming or reordering existing ones, and firing the FormUpdated / Group* / Field* events only for records that actually changed. Records absent from the definition are left untouched:

Forms::update('contact')
    ->name('Contact us')
    ->public()
    ->group('details', 'Your details', function (GroupBuilder $g): void {
        $g->field('name', 'Full name')->rules(['required']);
        $g->field('phone', 'Phone'); // added
    })
    ->save();

• Groups and fields are matched by key; a key that doesn’t exist yet is created.
• name(), public(bool) and expiresAt() are optional — anything you don’t set keeps its stored value.
• Fields are compared on name, type, help, autofill, options, validations, conditions, messages and order.
• Nothing is deleted — to remove a group or field, soft-delete its model.
• An unknown key throws FormNotFoundException.
