Table of Contents (TOC) and Legend

Default Table of Contents (TOC) and Legend

    Hi folks,

    I need help with the TOC Table of Content ArcScript posted on the arcscript page by Tom Hill. I am developing a Flex app outside of the Flex Viewer. I need to have the Group TOC and the legends. I was already able to put together the website with the map, the group TOC and the legend using the esri Legend component. What I need help is with the following:

    1 - Have one layer always visible (in my case the county layer)
    2 - Have all the other layers off when another layer (other than the layer that is always visible, the counties layer) is checked on
    3- Have the legend pop up for the layer that is checked on (right now I would have the legend visible for all the layers that are checked on, I just need to have one single for the one layer checked on)
    4- When there are two sublayers, the legends should be side-by-side not on top of one another vertically

    I am attaching the image of my web app, the TOC arcscript I usde for the group TOC and part of the script of my main app so far:

    Any help is greatly appreciated! I am new to Flex and ActionScript so I am not sure yet how to implement this! I love Flex ! Thanks!

Actually for the legend I would just have one legend (for the map that is showing, the only one checked and visible on the TOC  (besides the counties layer that does not need a legend)

Any ideas?

Can anybody offer any help for this? I know it would probably be easy for the Flex wizards we have here 🙂
