Hi,
A shortcode in a shortcode will most of the time not work well, because it breaks the html codes.
I can see you want to open a modal. Many / most plugins for modals include some form of triggering it via a link, class or some other way.
Maxbuttons can have extra classes, a custom link and some other options under advanced which mostly helps to solve the problem. You’ll have to find in the documentation of your plugin how this can be done.
We also have an example of how it can be done with one of the plugins, so you’ll get the idea of how it works : https://maxbuttons.com/how-to-open-a-popup-when-a-user-clicks-a-button/
I tried what was stated and did not work . What I am trying to accomplish is a button with a CTA to a shortcode if that makes sense.
I don’t know how your specific plugin works, but the general idea is the same; to find some way to trigger the CTA into action without using the shortcode.
You can put the shortcode and see how the link looks. Usually the stuff after the ? is important. Or you could ask the creator of the other plugin.
