Hi Ziaul,
yes, it is a little bit tricky. I try to record the problem.
1.) I use jalbum with the skin photoblogger, which offers an online shop. There are some more websites that will be opened. It starts with "Online Shop/index.html" which I put in the <raw HTML> element of pagebuilder like this:
<div class="container">
<iframe id="iframeshop" class="responsive-iframe" src="/jalbum/Online Shop/index.html" frameborder="0" overflow:scroll" ></iframe>
</div>
Now you have 4 categories to chose, for example you'll buy Poster... you go another level deeper. Now the URL is
"Online Shop/Poster/index.html" and here you see the shopping basket where I want to get the link to the popup.
But if it's to difficult, I will use the button I've made [AGB]
You can have a look in your browser: https://www.will-cassel.de/de/shop click on Zwergenposter and see the basket!
