I have tree loaded as below

1Home
    2.1 HS1
        2.1.1 Gallery1
    3.1 HS2
        3.1.1 Gallery3

My Goal is initially tree will be collpased and showing below output
1 Home
     +2.1 HS1
     +3.1 HS2

If I add Gallery 2.1.2 Gallery 2, After adding it It should expand 2.1 HS1 and 
show 2.1.2 Gallery 2 selected. HS2 should collapse. Below outout is expectd.

1Home
    2.1 HS1
        2.1.1 Gallery1
        2.1.2 Gallery2
    +3.1 HS2
