Layout problem

[NicoThomas]

I try to implement the layout like in the picture but have no luck with the forms on the left side.
Form1 should dock and autohide on the button of the Browser Form.

I would very much appreciate it if somebody could help me.

Nope, it should not. The auto-hide panel strip should appear in the left, not the bottom. Microsoft designs the layout years ago, and DPS just follows.

If you want something that special, fork this project and do your own work.
