`mj-accordion` is an interactive MJML component to stack content in tabs, so the information is collapsed and only the titles are visible. Readers can interact by clicking on the tabs to reveal the content, providing a great experience on mobile devices where space is scarce.

<aside class="notice">
  `mj-accordion-text` and `mj-accordion-title` are "ending tags", which means they can contain HTML code which will be left as it is, so they can contain HTML tags with attributes, but they cannot contain other MJML components. More information about ending tags <a href="#ending-tags">in this section</a>.

                Because emails with a lot of content are most of the time a very bad experience on mobile, mj-accordion comes handy when you want to deliver a lot of information in a concise way.

                Content is stacked into tabs and users can expand them at will. If responsive styles are not supported (mostly on desktop clients), tabs are then expanded and your content is readable at once.
