Direction Provider

Overview

Section titled “Overview”

Direction Provider cascades a reading direction ("ltr" or "rtl") to descendant primitives via a named cascading parameter (NaviusDirection). Direction-aware parts (roving focus, Slider, Scroll Area, menus) read the cascaded value and flip arrow-key semantics and layout for RTL. It renders no element of its own.

Anatomy

Section titled “Anatomy”
@using Navius.Primitives.Components.DirectionProvider


<NaviusDirectionProvider Dir="ltr">
    @* direction-aware primitives *@
</NaviusDirectionProvider>

Root

Section titled “Root”

Cascades the reading direction to descendants. Renders no DOM element.

Prop Type Default Description
Dir string "ltr" Reading direction cascaded to descendants ("ltr" or "rtl").
ChildContent RenderFragment? - Descendants that read the cascaded direction.

ARIA mechanism

Section titled “ARIA mechanism”

Direction Provider wires no ARIA attributes itself; it only cascades a direction value that descendant primitives use to present the correct experience to users reading right-to-left, including which arrow key moves focus forward. There are no keyboard interactions of its own. This mechanism is covered by the Playwright browser test suite.
