Popover

Popovers are similar to tooltips. They are small overlays that open on demand after a user interaction. The difference is that the popover can contain more content, without cluttering the page. They must be specified inside the overlay prop of an activator component (Button, Link or Pressable).

The library automatically applies the WAI-ARIA Popover Widget pattern to both the activator and the popover content.

Anchor to popoverpropsPopoverProps

Anchor to alignment alignment Default: 'center': Align the Popover in the axis determined by the position.
Anchor to id id string: A unique identifier for the component.
Anchor to maxInlineSize maxInlineSize < number | `${number}%` | 'fill' >: Adjust the maximum inline size.

number: size in pixels.

`${number}%`: size in percentages.

fill: takes all the available space.

See MDN explanation of maxInlineSize.
Anchor to minInlineSize minInlineSize < number | `${number}%` | 'fill' >: Adjust the minimum inline size.

number: size in pixels.

`${number}%`: size in percentages.

fill: takes all the available space.\

See MDN explanation of minInlineSize.
Anchor to onClose onClose () => void: Callback to run when the Popover is closed
Anchor to onOpen onOpen () => void: Callback to run when the Popover is opened
Anchor to padding padding <<>>: Adjust the padding.

To shorten the code, it is possible to specify all the padding properties in one property.

Examples:

base means blockStart, inlineEnd, blockEnd and inlineStart paddings are base

[base, none] means blockStart and blockEnd paddings are base, inlineStart and inlineEnd paddings are none

[base, none, loose, tight] means blockStart padding is base, inlineEnd padding is none, blockEnd padding is loose and blockStart padding is tight
Anchor to position position Default: 'blockStart': Position the Popover relative to the activator.

Alignment

'start' | 'center' | 'end'

MaybeResponsiveConditionalStyle

A type that represents a value that can be a conditional style. The conditions are based on the viewport size. We highly recommend using the `Style` helper which simplifies the creation of conditional styles. To learn more check out the [conditional styles](/api/checkout-ui-extensions/components/utilities/stylehelper) documentation.

T | ConditionalStyle<T, ViewportSizeCondition>

ConditionalStyle

conditionals
An array of conditional values.
```
ConditionalValue<T, AcceptedConditions>[]
```
default
The default value applied when none of the conditional values specified in `conditionals` are met.
```
T
```

export interface ConditionalStyle<
  T,
  AcceptedConditions extends BaseConditions = Conditions,
> {
  /**
   * The default value applied when none of the conditional values
   * specified in `conditionals` are met.
   */
  default?: T;
  /**
   * An array of conditional values.
   */
  conditionals: ConditionalValue<T, AcceptedConditions>[];
}

ConditionalValue

conditions
The conditions that must be met for the value to be applied. At least one condition must be specified.
```
AcceptedConditions
```
value
The value that will be applied if the conditions are met.
```
T
```

export interface ConditionalValue<
  T,
  AcceptedConditions extends BaseConditions = Conditions,
> {
  /**
   * The conditions that must be met for the value to be applied. At least one
   * condition must be specified.
   */
  conditions: AcceptedConditions;
  /**
   * The value that will be applied if the conditions are met.
   */
  value: T;
}

ViewportSizeCondition

viewportInlineSize
```
{ min: T; }
```

export interface ViewportSizeCondition<T = ViewportInlineSize> {
  viewportInlineSize: {min: T};
}

Use popovers if:

The intent is to ask the customer for information.
It’s possible to use at most two rows of input fields to get the information.
