Sorting data in coloums based on another coloum - Code Continuation

Hello All,
I wanted to know how to sort a list of data in a row based on a number in the colum next to it and then by Alphabetical order.

So for example Coloum I contains the numbers 2, 1.2 and 1.1
I need it so that everything if I says 1.1 then the coressponding J cell is placed in a list bellow A3. This should then be repeated for all values of 1.1. Then 1.2 should go in B3 and bellow and 2 should go in C3.

So far i've written this bit that collects and sorts data in J based on I, but im not sure how to continue it to split it up under the A,B,C coloums in the same alphabetical order.

Code so far

Range("A19:J250").Select
    ActiveWindow.SmallScroll Down:=-156
    Selection.Sort Key1:=Range("I20"), Order1:=xlDescending, Key2:=Range( _
        "J20"), Order2:=xlAscending, Header:=xlYes, OrderCustom:=1, MatchCase:= _
        False, Orientation:=xlTopToBottom, DataOption1:=xlSortTextAsNumbers, _
        DataOption2:=xlSortNormal
