Navigator to Listview

[subhajit]

Suppose I have created 3 spaces(Say A, B, C) in alfresco repository under 'sites'. Under A I have created 2 spaces like 1 and 2 and under B I have created 3 and under C I have created 4. Now alfresco navigator looks like following,

Sites
          –> A
                    –>1
                    –>2
          –> B
                    –>3
          –> C
                   –>4

Now what I want is that the whole structure will be in list with 2 columns,
    column1                                                              column2
         A(if I click A)                                                       1
         B                                                                         2
         C

    column1                                                             column2
         A                                                                       3
         B(if I click B)                     
         C

    column1                                                            column2
         A                                                                      4
         B                     
         C(if I click C)

just to give the following type of view,
