Hi Dave
It is possible, but the process is a little involved:
2. Click the "Create New" button at the top right
3. Configure the widget as you like
4. Click the "Create Widget" button
5. Copy the generated HTML code to the clipboard. Mine looks like this:
<a class="twitter-timeline" href="
https://twitter.com/Jermolene" data-widget-id="570677909237792768">Tweets by @Jermolene</a> <script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?'http':'https';if(!d.getElementById(id)){js=d.createElement(s);
js.id=id;js.src=p+"://
platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");</script>
6. Create a blank HTML file containing the following template with the Twitter widget embedded in the middle where indicated:
<html>
<body>
{{paste widget code here}}
</body>
</html>
7. Save the HTML file as (say) "myfeed.html" in the same folder as your TiddlyWiki HTML file
8. Embed the HTML file via an iframe such as:
<iframe src="myfeed.html" scrolling="no" frameborder="0" allowtransparency="true" height="350" height="460" style="border: none;"></iframe>
Let me know how you get on,
Best wishes
Jeremy
