Hi @ad0102 ,

You can write additional javascript code into your theme, so you can change the wording as you want. If you want to hide some elements, you can use CSS with the display: “none” attribute.
Please let me know more clearly the problem you are having, maybe give me a picture or link to your store so I can help you.
