public class SectionStack extends VLayout implements HasSectionHeaderClickHandlers
A container that manages a list of sections of widgets, each with a header. Sometimes called an "Accordion".

SectionStack can be configured so that only one section is visible at a time (similar to MS Outlook's left-hand Nav), or to allow multiple sections to be visible and share the available space. For further details, see `visibilityMode`.

To ensure all sections are accessible, you may need to set `overflow` to enable scrolling.

  - ### setSectionHeaderClass

    public SectionStack setSectionHeaderClass(String sectionHeaderClass) throws IllegalStateException
    Widget to use for section headers.

    Must be a subclass of either `ImgSectionHeader` or `SectionHeader`. The default class used depends on the skin; `SectionHeader` is the simpler and lighter-weight class and uses CSS styling rather than image-based styling, and is recommended for most use cases.

    If you create a custom section header class in Java, enable `Reflection` to allow it to be used.

    Alternatively, you can use the SmartClient class system to create a simple SmartClient subclass of either SectionHeader or ImgSectionHeader for use with this API - see the `Skinning Guide` for details.

    If you override event handlers on your custom SectionHeader or radically change it's structure such that the default event handling no longer works, you can call `sectionHeaderClick()` to replicate the built-in expand/collapse handling for clicking a section header.

    Note : This is an advanced setting

    Parameters:
      `sectionHeaderClass` - New sectionHeaderClass value. Default value is "SectionHeader"
    Returns:
      `SectionStack` instance, for chaining setter calls
    Throws:
      `IllegalStateException` - this property cannot be changed after the component has been created

  - ### setShowExpandControls

    public SectionStack setShowExpandControls(Boolean showExpandControls)

  - ### setDefaultProperties

    public static void setDefaultProperties(SectionStack sectionStackProperties)
    Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties set on the SmartGWT class instance passed to this function before its underlying SmartClient JS object was created. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

    Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

    Parameters:
      `sectionStackProperties` - properties that should be used as new defaults when instances of this class are created
    See Also:
      - `SGWTProperties`
