Multiselect object with disabled entries inside.

Hello,

I have a multiselect object :
{
view: “multiselect”,
name: ‘mus_id’,
id : “musId”,
label: “test”,
labelPosition: “top”,
options: {
css: “app_list”,
body: {
view: “list”,
id: “musIdList”,
template: “#name#”
}
},
},

For the moment I load data from server and it is OK.
My question is :
Is it possible to have disabled entries in combo , just for consulting, and at the same time other that we can click or unclick ?
Is it possible to match with properties “disabled” or “enabled” from server to represent this object ?

Thanks
