tables follows according specifications categories table:

        id name         1 gender         2 role 

sub categories table:

         id categoryid name          1  1          male          2  1          femal          3  2          admin          4  2          user 

you need this:

mapper.addmap<customer, customerinput>(src => {     var res = new customerinput();     res.injectfrom(src); // maps simple properties same name , type     res.coll = src.collection.select(srcitem => mapper.map<collitemrestype>(srcitem)     return res; });
