## Interface IsCollapsible

- All Known Implementing Classes:
    ButtonBase, ButtonCellBase, TextButton, TextButtonCell

      public interface IsCollapsible

  Indicates that a UI component can be collapsed next to another UI component, thus sharing a common border. This allows UI components to appear flush against each other without extra thick borders.

  Before collapse:

         ---------    ----------    ---------
        | ButtonA |  |  ButtonB |  | ButtonC |
         ---------    ----------    ---------

  After collapse:

         -----------------------------
        | ButtonA | ButtonB | ButtonC |
         -----------------------------

  In the above example, ButtonA has right-side collapsed, ButtonB has both left and right-side collapsed, and ButtonC has left-side collapsed.
