Advanced

Disable on Components Select in which frontend components NOT to enable the use of this extension.
Remove in Disabled Components If selected, the plugin syntax will get removed from the component. If not, the original plugins syntax will remain intact.
Enable in administrator If enabled, the plugin will also work in the administrator side of the website.

Normally you will not need this. And it can cause unwanted effects, like slowing down the administrator and the plugin tags being handled in areas you don't want it.
Place HTML comments By default HTML comments are placed around the output of this extension.
These comments can help you troubleshoot when you don't get the output you expect.
If you prefer to not have these comments in your HTML output, turn this option off.
Use Media Versioning Select to add the extension version number to the end of media (js/css) urls, to make browsers force load the correct file.
Load Bootstrap Framework Disable to not initiate the Bootstrap Framework.

Tooltips needs the Bootstrap Framework to function. Make sure your template or other extensions load the necessary scripts to replace the required functionality.
