"Show More" button & floating window

Happy thanks giving everyone!

Please see attached images for details, I photoshopped couple renderings showing what I'm looking for, appreciate who can help me on this issue, I'm with business plan:

I'm looking to put dozens of review cards/testimony in one section with slider buttons, would be great if i can keep all cards the same size, and integrate "show more" button with long texts. a floating window showing full texts when you click "show more" button.

Please let me know thank you!

Forgot to attach one of my rendering, see below:

Hi,

I think this is possible, but you will need a Business Plan or higher

I did a similar thing, but with List Section Simple

pass: abc

You can add a List Carousel, add some text like screenshot, next add a bold text Read More, next add some more text after Read More

Next, share link to page where you added List Carousel, we will try some custom code

In case you want to click Read More >> Show a popup. You can use Lightbox Plugin. (affiliate link)
