Add possible to pass another value to initialState param

[gsnunes]

In my feature I need to instance the treegrid and keep the current state.
But currently, when I add one more row and apply the treegrid, the another rows are open or close.

I think in accept another value like "keep" or simply false. Currently is only ("expanded" and "collapsed").
