For more information see [SplitContainer Layout](/componentone/docs/win/online-splitcontainer/splitcontainerlayout). * **Multiple Panels**
You can easily add, remove, and modify multiple panels through the **C1SplitContainer.Panels Collection editor**. For more information see [Adding Multiple Panels to the C1SplitContainer](/componentone/docs/win/online-splitcontainer/splitcontainerforwin3/addingmultiplepanels). * **Unlimited Nesting**
Organize massive amounts of data into one page using SplitContainer’s nesting feature. **SplitContainer for WinForms** enables you to nest multiple splits of any orientation type as well accommodate the resizing for the nested splitters when you resize the panel. See [Compound Split](/componentone/docs/win/online-splitcontainer/splitcontainerlayout/splitcontainerlayout1/compoundsplit1) for more information. * **Collapsed or Expanded Splitter Bar ToolTip**
Create a more user-friendly Windows application by adding a ToolTip to the collapsed or expanded splitter bar. The ToolTip can let end-users know to click on the expander button to expand the hidden panel or click on the collapsed button to hide the panel. See [Expander Button](/componentone/docs/win/online-splitcontainer/splitcontainerelemen/expanderbutton) for more information.
