# UIButtonRowElement

***

Represents a row of buttons.

It is useful to group buttons together and align them.

Unlike on [UIGridContainerElement](/js-sdk-api-reference/ui/uigridcontainerelement.md), buttons do not expand to fill the container. Instead, they use the space they need and are wrapped to the next line when they overflow.

### Label

A label can be added to the button row using the `label` property.

```typescript
{
  type: "ButtonRow",
  label: "Zoom control",
  items: [
    { type: "Button", label: "Increase", onClick: () => {} },
    { type: "Button", label: "Decrease", onClick: () => {} },
  ],
}
```

### Alignment

It is possible to align the button row to the start or end of the container using the `align` property.

#### Start alignment

```typescript
{
  type: "ButtonRow",
  align: "start", // default value
  items: [
    { type: "Button", label: "Button 1", onClick: () => {} },
    { type: "Button", label: "Button 2", onClick: () => {} },
  ],
}
```

#### End alignment

```typescript
{
  type: "ButtonRow",
  align: "end",
  items: [
    { type: "Button", label: "Button 1", onClick: () => {} },
    { type: "Button", label: "Button 2", onClick: () => {} },
  ],
}
```

### Overflow

When buttons overflow the container, they are wrapped to the next line.

```typescript
{
  type: "ButtonRow",
  items: [
    { type: "Button", label: "Button with a very long text", onClick: () => {} },
    { type: "Button", label: "Button 2", onClick: () => {} },
    { type: "Button", label: "Button 3", onClick: () => {} },
  ],
}
```

### With Grid container

[UIGridContainerElement](/js-sdk-api-reference/ui/uigridcontainerelement.md), as a generic container, can render [UIButtonRowElement](/js-sdk-api-reference/ui/uibuttonrowelement.md) as well.

In this example, the combination of [UIGridContainerElement](/js-sdk-api-reference/ui/uigridcontainerelement.md) and [UIButtonRowElement](/js-sdk-api-reference/ui/uibuttonrowelement.md) is used to layout a footer where the buttons are aligned to the end of the container and the text is at the start.

```typescript
{
  type: "Grid",
  grid: "auto-flow / 1fr auto",
  rowItemsJustify: "space-between",
  rowItemsAlign: "center",
  items: [
    { type: "Text", content: "Continue?" },
    {
      type: "ButtonRow",
      align: "end",
      items: [
        { type: "Button", variant: "transparent", label: "Cancel", onClick: () => {} },
        { type: "Button", variant: "filled", tint: "primary", label: "Continue", onClick: () => {} },
      ]
    },
  ],
}
```
