## Skeleton mode

The `isSkeleton` property defines element behavior when interacting with the parent Skeleton component.

**Possible values:**

- `true` — element displays as skeleton when Skeleton is in active state
- `false` — element becomes invisible when Skeleton is in active state

Works in conjunction with the Skeleton component to control visibility and display mode of child elements. When parent Skeleton has `active=false`, all child elements display normally regardless of `isSkeleton` value. When `active=true`, elements with `isSkeleton=true` are shown as skeleton placeholders, while elements with `isSkeleton=false` are completely hidden.

```html
<!-- Element will display as skeleton -->
<Skeleton active>
  <ListItem isSkeleton text="Loading..." />
</Skeleton>

<!-- Element will be hidden -->
<Skeleton active>
  <ListItem :isSkeleton="false" text="Hidden text" />
</Skeleton>
```
