Hi! I'm building the next LAYERTREE:

layertree = [

{text: "Background images",

expanded: false,

children: [

{text: "Orthophoto 1:5000",

icon: 'Images/blanc.gif',

expanded: false,

checked: false,

layerName: "Ortho5m"},

{text: "Topographic map 1:5000",

icon: 'Images/blanc.gif',

expanded: false,

checked: false,

layerName: "Topo5m"}]

{text: "Street",

expanded: false,

children: [

{text: "Street names",

icon: 'Images/blanc.gif',

checked: false,

layerName: "Streets"},

{text: "Street numbers",

icon: 'Images/blanc.gif',

checked: false,

layerName: "StreetNumbers"}]

{text: "Cadastre",

expanded: true,

children: [

{text: "Blocks",

icon: 'Images/blanc.gif'

checked: true,

layerName: "BlocksUrbans07"},

{text: "Plots",

icon: 'Images/blanc.gif',

checked: false,

layerName: "PlotsUrbans07"}]

}

]

I wish that "Background images", "Street" and "Cadastre" were options buttons. This means than the user can only select one. Once selecte one, the user will be able to choose the corresponding layers belonging to the option button. For example, if the user chooses "Background images" (therefore, he WILL NOT BE ABLE choose "Street" and "Cadastre"), he will be able select "Orthophoto 1:5000" and "Topographic map 1:5000. Thus, the user will not be able to mix the information of the three groups.
If I have not explained well, I can extend the detalis.
Thank your very much and best regards.
