Use HTML in tabs?

How can I use HTML in tabs?

For example, an item page for football players would include a tab that pulls in their latest tweets using Twitter's embed code (Twitter Publish):

<a class="twitter-timeline" href="https://twitter.com/TwitterDev?ref_src=twsrc%5Etfw">Tweets by TwitterDev</a> <script async src="https://platform.twitter.com/widgets.js" charset="utf-8"></script>

You can't. XenForo does NOT allow posting HTML content via the Core Editor. There are a couple HTML addons available for XF1, however, I can't guarantee that they will work with Showcase out of the box (they SHOULD, but at least one of them (Lukes) is built specifically for Threads only and requires customization to get it to work with other addons).
Would something like this work?


This add-on is designed to allow posting of html in your forum. It adds a html button to the Rich Text Editor, which then it will parse the html in posts, threads, signatures, personal conversations and in all the other third party add ons that make use of the the Rich Text Editor such as my Articles Manager add on, or the Resource Manager to name a few.
According to the resource description, it will do what you are wanting to do (which is to add HTML into the Core XF Editor and have that HTML parsed). If it works for the XFRM, I can't see any reason why it won't work with Showcase (and I am pretty sure that is the addon that a lot of SC license holders use for adding HTML content to Showcase).
I will try it out and report back. I wanted to avoid using Luke's add-on since support for that has dropped off.
