What I'm trying to do is uncheck other not selected items while the list remains open. I don't know how to access the other options and do that other than through the initialize function.

So, basically something like the Minimap tracking menu? Might be some hints in that code.

function MiniMapTracking_Update()
    UIDropDownMenu_Refresh(MiniMapTrackingDropDown);
end
 
function MiniMapTrackingDropDown_OnLoad(self)
    UIDropDownMenu_Initialize(self, MiniMapTrackingDropDown_Initialize, "MENU");
    self.noResize = true;
end
 
function MiniMapTracking_SetTracking (self, id, unused, on)
    SetTracking(id, on);
    UIDropDownMenu_Refresh(MiniMapTrackingDropDown);
end
 
function MiniMapTrackingDropDownButton_IsActive(button)
    local name, texture, active, category = GetTrackingInfo(button.arg1);
    return active;
end
 
function MiniMapTrackingDropDown_IsNoTrackingActive()
    local name, texture, active, category;
    local count = GetNumTrackingTypes();
    for id=1, count do
        name, texture, active, category  = GetTrackingInfo(id);
        if (active) then
            return false;
        end
    end
    return true;
end
 
function MiniMapTrackingDropDown_Initialize()
    local name, texture, active, category;
    local count = GetNumTrackingTypes();
    local info;
    
    info = UIDropDownMenu_CreateInfo();
    info.text=MINIMAP_TRACKING_NONE;
    info.checked = MiniMapTrackingDropDown_IsNoTrackingActive;
    info.func = ClearAllTracking;
    info.icon = nil;
    info.arg1 = nil;
    info.isNotRadio = true;
    info.keepShownOnClick = true;
    UIDropDownMenu_AddButton(info);
    
    for id=1, count do
        name, texture, active, category  = GetTrackingInfo(id);
 
        info = UIDropDownMenu_CreateInfo();
        info.text = name;
        info.checked = MiniMapTrackingDropDownButton_IsActive;
        info.func = MiniMapTracking_SetTracking;
        info.icon = texture;
        info.arg1 = id;
        info.isNotRadio = true;
        info.keepShownOnClick = true;
        if ( category == "spell" ) then
            info.tCoordLeft = 0.0625;
            info.tCoordRight = 0.9;
            info.tCoordTop = 0.0625;
            info.tCoordBottom = 0.9;
        else
            info.tCoordLeft = 0;
            info.tCoordRight = 1;
            info.tCoordTop = 0;
            info.tCoordBottom = 1;
        end
        UIDropDownMenu_AddButton(info);
    end
end
