Property Access type Description

element

Read-only

Gets the DOM element that hosts the SplitViewPaneToggle control.

splitView

Read/write

Gets or sets the DOM element of the SplitView that is associated with the SplitViewPaneToggle control. When the SplitViewPaneToggle is invoked, it'll toggle this SplitView's pane.

 

Remarks

The SplitView control is not required to be used with a "Hamburger" button, but that’s the most common and intended use case. The SplitViewPaneToggle provides that "Hamburger" control.

The SplitViewPaneToggle control has two use modes depending on whether or not the app has provided a SplitView control.

SplitViewPaneToggle keeps the SplitView, the aria-controls attribute, and the aria-expands attribute in sync. In this use case, apps typically won't listen to the invoked event, although it's still fired. This is the recommended usage.

2. SplitView not provided

SplitViewPaneToggle provides button visuals and fires the invoked event. The app intends to do everything else:

  • Set the SplitViewPaneToggle's aria-controls attribute
  • Keep the SplitViewPaneToggle, the SplitViewPaneToggle's aria-expanded attribute, and the SplitView in sync by:
    • Handling the SplitViewPaneToggle’s invoked event
    • Handling the SplitViewPaneToggle’s aria-expanded attribute being mutated (e.g. by screen readers)
    • Handling the SplitView opening and closing

Known limitations

SplitViewPaneToggle is required to be instantiated on a button element. Instantiating on any other element will throw an exception.
