Issue with mapicons ?

I am wandering if this is i have to put the email address and the url of the site in the html description...
I saw in the doc it can cause breaks in the map with emails... how to avoid this as the person who are going to fill the marker list will not be able to do the "transform" from the code page...
Maybe if i deactivate the email plugin of joomla on the article who include the map ?

That's it.
If i add {emailcloak=off} and put the map with a loadposition in the content, it works well..

Yes, if you want to add emails into infowin content, you should disable email cloaking joomla plugin, or write a little JS script in this field to concatenate strings to get email by its format (like cloak plugin does it).
And you can add any HTML text into additional HTML field. You can also use infowin toolbar and connect placemark to an article, to placemark detail page and so on
