I'm creating an accessible PDF on InDesign and wanted to add pop-up windows (when you set a button to open/close a pop-up inside the PDF). However, I tested it and it seems there's not a way to make these accessible. I'd like to know if there is a way to make it accessbile (so that the screen reader reads the pop-up when it opens up), or if this is really a non accessible feature.

Forget accessibility issues, show/hide buttons is a very, very wonky feature even with Acrobat or Reader on a desktop. My advice is to skip it and find a better way to present your information.
Hello! Unfortunatelly this isn't an option, one of the main demands for this material is accessibility, so that everyone can understand it and read it. I brought my doubt here because I couldn't find an aswer anywhere else, but if it's not an accessible feature, then I'll just have to make it without the buttons 😕
What do you mean it's not an option? It's your only option if you want to use a PDF.
In short if your main demand is accessibility, you can create this as an accessible PDF but without the show/hide buttons. Even if they worked (sketchy at best), I doubt they fall under WCAG compliance.
Since it's a PDF file, it falls under PDF/UA-1 compliance for accessibility, not WCAG (Web Content Accessibility Guidelines). See the law at US Access Board, https://www.access-board.gov/ict/#504-authoring-tools
But regardless of accessibility, pop-ups and other interactives just don't work well enough in PDFs. Period. So as others have said, find another way. One idea: use an internal cross-reference hyperlink to another section of the PDF, perhaps to a glossary at the back of the PDF if you're explaining terms. But be sure to hyperlink back to the original reference.
Eventually we'll have this type of interactivity in PDFs — and accessible, too — but we're a few years away from that.
Hello guys, thanks for the answers! The priority is for it to be accessible, so I'll just use other resources as hyperlinks as you said. I posted the question just in case there was a way to make pop-ups accessible that I didn't know of. However, thanks for clarifying 🙂
