javascript - WordPress InnerBlocks Gutenberg don't save correct

one text

Solution:

The issue how the classes are being applied in save() of wpptheme/faq-section. CSS classes in React should be passed in with "className" property, unlike vanilla HTML.

Updated save() for wpptheme/faq-section:

...
    save() {

        return (
            <div className="container my-4 my-md-5">
                <div className="row">
                    <div className="col-12">
                        <div className="accordion" id="faq">
                            <div>
                                <InnerBlocks.Content />
                            </div>
                        </div>
                    </div>
                </div>
            </div>
    );
}
