Here is the code originally from my own server

pawn Код:

CMD:marker(playerid, params[])
{
    ShowPlayerDialog(playerid,1240,DIALOG_STYLE_LIST,"Map Markers","Show Marker\nHide Marker","Ok", "Cancel");
    return 1;
}


public OnDialogResponse(playerid, dialogid, response, listitem, inputtext[])
{
    switch(dialogid)
    {
        case 1240:
        {
            if(!response)
            {
            SendClientMessage(playerid, 0xFF0000FF, "You cancelled.");
            return 1;
            }

            switch(listitem)
            {
                case 0:
                {
                    for(new i=0; i<MAX_PLAYERS; i++) SetPlayerMarkerForPlayer( i, playerid, GetPlayerColor( playerid ) ); //from wiki
                    return SendClientMessage(playerid, 0x80FF00AA, "Your marker is now seeable for everyone.");
                }
                case 1:
                {
                    for(new i=0; i<MAX_PLAYERS; i++) SetPlayerMarkerForPlayer( i, playerid, ( GetPlayerColor( playerid ) & 0xFFFFFF00 ) ); //from wiki
                    return SendClientMessage(playerid, 0x80FF00AA, "Your marker is now invisible for everyone.");
                }
            }
        }
    }
    return 1;
}

I think this will help this code was made by Jeffry he made me that code but without dialog i converted into dialog for you.
