We love Tilda! It allows you to create a website really quick, download it and get really good looking pages even if you don't have any design skills. All Tilda pages have good typography, styles and adaptive design.
Our addon JS code should be placed to the HEAD zone of your Tilda website.
Open Dashboard/your site/Site settings/more/html_code_for_head-zone/edit_code. Put the JS reference code for external websites into the <HEAD> zone of your Tilda-based website and save it.
Tilda is a visual editor. Since all elements and links are inserted through the CMS-like interface, you should use Tilda external websites links codes.
Copy "Link for button, text or image" and paste it to the link field for image, button or text link in your external Tilda website to add "add-to-cart" function.
Popup tooltips for links
You can set any popup tooltip text for links in your external websites. To do that just type any text after the product number and a hyphen #addtocart-product-37- in the link field.
If you don't need a tooltip just delete the text after the hyphen.
