[maplab-users] RE: "Long legend" issues...

[Doyon, Jean-Francois]

Yup, you can either use a DIV or an IFRAME with a scroll bar, so you can
just scroll the legend, but not the entire mapping interface.

We'll be implementing this this fall on the Atlas of Canada.

We resisted doing this for a long time due to browser compatibility issues,
but now it seems we can do it reliably (No more NN4!).

You use the "overflow" style on the DIV to get a scrollbar ...

Subject: "Long legend" issues...

Dear All,


I'm not still able to resolve issues referred to "long legend" problems
generated by MapServer when you use several layers.
Main problem is that when generated legend is very long you are forced to
scroll relative map page.
Specer Cox in his post (
http://lists.maptools.org/pipermail/maplab-users/2005-April/001689.html )
suggested to use <div> element to resolve this issue but, sincerely, I don't
understand WHERE "div" element has to place...
Another suggested solution comes from Jean-Francois Doyon: in his post (
http://lists.dmsolutions.ca/pipermail/maplab-users/2002-November/000369.html
) he suggested to  throw the legend into an <iframe>... again I don't
undestand where (and how) to place this element...
I think and suggest, as ideal solution and in order of complexity:

a) long legend should be divided in two or three column in left side of main
map page;
b) legend should be put in a frame where one may to scroll only it;
c) legend may be shown entirely but with possibility to hide or show layers
expanding or collapsing 
   groups shown as tree structure.

How to make it possible? May someone help me?.

Many thanks.

- Exp.
