# UIFlexibleSpaceElement

***

Represents a flexible space element in a container.

When rendered...

* inside [UIGridContainerElement](/js-sdk-api-reference/ui/uigridcontainerelement.md), it will add extra gap between items. It can be controlled by `grid` property.
* inside [UIPanelElement](/js-sdk-api-reference/ui/uipanelelement.md) `body` or `footer`, since they work as vertically stacks, it will add extra gap between items.

## Examples

Paragraphs with a flexible space between makes them more visually separated.

```typescript
{
  type: "Panel",
  body: [
    { type: "Paragraph", text: "Paragraph 1" },
    { type: "FlexibleSpace" },
    { type: "Paragraph", text: "Paragraph 2" },
  ],
}
```

Horizontal stack of buttons with a flexible space between makes them more visually separated.

```typescript
{
  type: "Grid",
  grid: "auto-flow / auto 1fr auto",
  items: [
    { type: "Button", label: "Button 1", onClick: () => {} },
    { type: "FlexibleSpace" },
    { type: "Button", label: "Button 2", onClick: () => {} },
