I have a form with some fields, and below that a list of children. This list of children is displayed as a tree. When I open a record (switch the view to form-mode), the tree is default fully collapsed to 1 level. But now I want the tree to be fully expanded when I open the form, so I don’t need to expand the children myself. The level of depth is max. 3.
It there an XML option which defines this?

I found `tree_state` and added it to the `.....`. It seems that this is user specific.
Hopefully there is also something which is working globally and just expand the tree.

No there is not option to always expand a tree because a tree can have an infinite number of level if it is recursive for example.
But you can extend the `get` method of `ir.ui.view_tree_state` to return an expanded state for your model.

Thanks! For me, adding the tree\_state to the XML is the most easy solution and when clearly communicated with the users it should be enough for now. First let them work with it for some months if they still complain, we can extend the `get` method 😄
