Hi there,
Accordion items themselves are not the issue. If all of the accordion content is included in the page's HTML when the page loads, LLMs and search engines can usually read it, even if the sections are collapsed.
The problem occurs when the accordion content is loaded only after a user clicks it (via JavaScript/AJAX). In that case, some AI crawlers may only see the initial HTML and miss the dynamically loaded content. That's why LLM can't read the content until click the accordion. Cause, by default it hidden.
