I think you can solve the problem by usage of rowattr if you want to make the whole row bold (see the answer ). You can assign additional class or style attribute on the specified row. Alternatively you can use cellattr to assign class or style only on the cell, for example only on the cell in "menu" column (see the answer ).
I used standard grids in the referenced answers, but you can use rowattr and cellattr in the same way with TreeGrids. The access to the columns parent level and isLeaf existing in the TreeGrid can be helpful for you in the implementation.
You just have to skope the 'first-child' of your . Css declaration.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
