When the filterable property of the Native DropDownList is set to "true" the keyboard navigation is not working as expected. When the arrow up/down button is pressed in opened DropDownList, the selection in the popup is changed with two steps instead of one.
On press of the up/down arrow key, the selection in the DropDownList's popup should be changed with one step, instead of two
Currently, the popup of the DropDownList component opens only at the bottom of the component.
It will be a very nice feature if the Native DropDownList has a property that can configure the popup of the component to appear above its input.
This functionality will also be useful in scenarios where the DropDownList(DDL) is positioned at the bottom of a page. With the current implementation, when the DDL popup is expanded part of its items are hidden by the page borders.
When the DropDownList is focused and NOT expanded use the "Left/Right/Up/Down" arrows to change the selection in the component. The value in the DropDownList is changing but not being announced by the screen readers.
The changed DropDownList value should be announced no matter the way the value has been changed.
The record that matches the search criteria of the AutoComplete is highlighted in the popup but the data is not scrolled to this highlighted record.
The data in the AutoComplete popup should be scrolled to the highlighted element
