Я пытаюсь создать складное меню в r уценке.
Я создал воспроизводимый пример с 5 аккордеонами. Внутри этих аккордеонов я хочу показать сюжет и таблицу данных, которые связаны объектом SharedData. Когда уценка связывает документ, объект с данными не виден.
Пример с меню исходит из: https://www.w3schools.com/howto/howto_js_accordion.asp
Есть ли способ построить вывод данных с данными? Проблема заключается в этой строке кода:
htmltools::tagList(list(table))," \n",
.Rmd

title: "Collapsibles/Accordion Menu"
output:
html_document:
css: stylesheet.css
