Dear Daniel,
there it is
Creating your own TinyMCE Templates:
1. create your own .html Template and save at /media/editors/tinymce/templates/
Example: hotspot.html
<p><span style="text-decoration: underline; font-size: large;"><strong>Test Template</strong></span></p>
<p></p>
<p>Table:</p>
<table border="0">
<tbody>
<tr>
<td>Head1</td>
<td>Text1</td>
</tr>
<tr>
<td>Head2</td>
<td>Text2</td>
</tr>
</tbody>
</table>
2. edit /media/editors/tinymce/templates/ template_list.js to load your Template
Example:
["HotSpot", "media/editors/tinymce/templates/hotspot.html", "HotSpot Example"],
3. clean your Browser cache
4. open your Add HotSpot site and you'll find the new created template there:
I have not found a way to auto insert the Template while page/TinyMCE load, but there is another Joomla Plugin called Content Templater doing this
Kind regards Torsten
