# StickyStackRegistration

## Properties

### order {#order}

Sort order within the zone (ascending, top to bottom). May be reactive to reorder bars at runtime. Defaults to `0`.

Type: `MaybeRefOrGetter`

Source: `client/lib/use/useStickyStack.js:42`

### reveal {#reveal}

This bar's reveal behavior: a strategy string or a boolean, or a ref/getter of either for a reactive reason (for example, reveal a bulk-action bar only while there is a selection). When omitted, the bar stays visible (`always`).

Type: `MaybeRefOrGetter`

Source: `client/lib/use/useStickyStack.js:43`

### zone {#zone}

The zone the bar belongs to. Fixed at registration time. Defaults to `top`.

Type: [StickyZoneName](/v3/reference/api/js/use/useStickyStack/types/StickyZoneName.md)

Source: `client/lib/use/useStickyStack.js:41`
