Get the legend in mapguide

[Anonymous]

Good morning everybody,

I would like to know if there is solution (with PHP or Javascript) to get exactly the same legend displayed with the map in the web browser. I would like to display it in a pop-up or in another web page.

Otherwise, is there a search engine in this forum? (because there is a lot of topics!!)

Thanks in advance

Hum... The search engine works now. Sorry
