my requirement is to clone an existing account with all the fields as well as related list.
it should open in an edit mode so that user selects to save it or not. (edit mode so that if they want to make any changes)

my trigger :

trigger TestClone on Account (after insert) {
   Account [] accToSave = new Account[]{};
   
   if(checkRecursive.runOnce()){

        // query accounts and store by there name to lookup it up quickly
        Map<Id,Account> accountMap = new Map<Id,Account>([  Select  Id, Name, Description, Phone, Fax  
                                                        From Account 
                                                        Where Id IN: trigger.new]);

        // clone
        for (Account acc : trigger.new){   
            Account Clone = new Account();  
            Clone.Name =  acc.Name;
            Clone.Type =  acc.Type;
            Clone.Phone = acc.Phone;
            Clone.Fax =  acc.Fax;
            Clone.Description =  acc.Description;

            accToSave.add(Clone);
        }

        insert accToSave;

    }
}

class:
public Class checkRecursive{
    private static boolean run = true;
    public static boolean runOnce(){
        if(run){
            run=false;
            return true;
        }else{
            return run;
        }
    }
}
