<h5>Getting Started</h5>
|
|
<p>
|
|
CascadeSelect requires a value to bind and a collection of arbitrary objects with a nested hierarchy. <i>optionGroupLabel</i> is used for the text of a category and <i>optionGroupChildren</i> is to define the children of the category.
|
|
Note that order of the <i>optionGroupChildren</i> matters and it should correspond to the data hierarchy.

<p>
|
|
Value to describe the component can either be provided with <i>aria-labelledby</i> or <i>aria-label</i> props. The cascadeselect element has a <i>combobox</i> role in addition to <i>aria-haspopup</i> and
|
|
<i>aria-expanded</i> attributes. The relation between the combobox and the popup is created with <i>aria-controls</i> that refers to the id of the popup.
|
|
</p>
|
|
<p>
|
|
The popup list has an id that refers to the <i>aria-controls</i> attribute of the <i>combobox</i> element and uses <i>tree</i> as the role. Each list item has a <i>treeitem</i> role along with <i>aria-label</i>,
|
|
<i>aria-selected</i> and <i>aria-expanded</i> attributes. The container element of a treenode has the <i>group</i> role. The <i>aria-setsize</i>, <i>aria-posinset</i> and <i>aria-level</i> attributes are calculated implicitly and
|
|
added to each treeitem.
