# Coveo ResultList Component (CoveoResultList)

The `ResultList` component is responsible for displaying query results by applying one or several result templates (see Result Templates).

It is possible to include multiple `ResultList` components along with a single `ResultLayout` component in a search page to provide different result layouts (see Result Layouts).

This component supports infinite scrolling (see the `enableInfiniteScroll` option).

## Component Options

### autoSelectFieldsToInclude

autoSelectFieldsToInclude: boolean

- Defined in ui/ResultList/ResultList.ts :226

Whether the `ResultList` should scan its result templates to discover which fields it must request to be able to render all results.

Setting this option to `true` ensures that the Coveo Search API does not return fields that are unnecessary for the UI to function.

If you set this option to `true`, the fields referenced in your result folding templates won't be automatically resolved. In such a case, you must manually specify those fields using the `fieldsToInclude` option.

Notes:

- Many interfaces created with the JavaScript Search Interface Editor explicitly set this option to `true`.
- You cannot set this option to `true` in the Coveo for Sitecore integration.

Default

  `false`

Markup configuration example(s) :

    data-auto-select-fields-to-include='true'
    data-auto-select-fields-to-include='false'

### enableInfiniteScroll

enableInfiniteScroll: boolean

- Defined in ui/ResultList/ResultList.ts :161

Whether to automatically retrieve an additional page of results and append it to the results that the `ResultList` is currently displaying when the user scrolls down to the bottom of the `infiniteScrollContainer`.

See also the `infiniteScrollPageSize` and `enableInfiniteScrollWaitingAnimation` options.

It is important to specify the `infiniteScrollContainer` option manually if you want the scrolling element to be something else than the default `window` element. Otherwise, you might find yourself in a strange state where the framework rapidly triggers multiple successive query.

Default

  `false`

Markup configuration example(s) :

    data-enable-infinite-scroll='true'
    data-enable-infinite-scroll='false'

### enableInfiniteScrollWaitingAnimation

enableInfiniteScrollWaitingAnimation: boolean

- Defined in ui/ResultList/ResultList.ts :203

Whether to display the `waitingAnimation` while fetching additional results.

Only effective when

  `enableInfiniteScroll` is truthy

Default

  `true`

Markup configuration example(s) :

    data-enable-infinite-scroll-waiting-animation='true'
    data-enable-infinite-scroll-waiting-animation='false'

### enableScrollToTop

enableScrollToTop: boolean

- Defined in ui/ResultList/ResultList.ts :273

Whether to scroll back to the top of the page when the end-user:

- interacts with a facet when `infiniteScrollContainer` is set to `true`
- interacts with the `Pager` component when `infiniteScrollContainer` is set to `false`

Note: Setting this option to `false` has no effect on dynamic facets. To disable this behavior on a `DynamicFacet` component, you must set its own `enableScrollToTop` option to `false`.

Default

  `true`

Available since

  July 2019 Release (v2.6459)

Markup configuration example(s) :

    data-enable-scroll-to-top='true'
    data-enable-scroll-to-top='false'

### fieldsToInclude

fieldsToInclude: IFieldOption[]

- Defined in ui/ResultList/ResultList.ts :244

A list of fields to include in the query results.

If you set the `autoSelectFieldsToInclude` option to `true`, the Coveo Search API returns the fields you specify for this option (if those fields are available) in addition to the fields which the `ResultList` automatically requests. Note that the `autoSelectFieldsToInclude` option doesn't automatically request fields for folding templates; in such a case, you must manually specify fields using this option to avoid empty results.

If you set the `autoSelectFieldsToInclude` option to `false`, the Coveo Search API only returns the fields you specify for this option (if those fields are available).

If you set the `autoSelectFieldsToInclude` option to `false` and leave this option undefined, the Coveo Search API returns all available fields.

### infiniteScrollContainer

infiniteScrollContainer: HTMLElement

- Defined in ui/ResultList/ResultList.ts :194

The element that triggers fetching additional results when the end user scrolls down to its bottom.

You can change the container by specifying its selector (e.g., `data-infinite-scroll-container-selector='#someCssSelector'`).

By default, the framework uses the first vertically scrollable parent element it finds, starting from the `ResultList` element itself. A vertically scrollable element is an element whose CSS `overflow-y` attribute is `scroll`.

This implies that if the framework can find no scrollable parent, it uses the `window` itself as a scrollable container.

This heuristic is not perfect, for technical reasons. There are always some corner case CSS combination which the framework will not be able to correctly detect as 'scrollable'.

It is highly recommended that you manually set this option if you wish something else than the `window` to be the scrollable element.

Only effective when

  `enableInfiniteScroll` is truthy

### infiniteScrollPageSize

infiniteScrollPageSize: number

- Defined in ui/ResultList/ResultList.ts :169

The number of additional results to fetch when the user scrolls down to the bottom of the `infiniteScrollContainer`.

Only effective when

  `enableInfiniteScroll` is truthy

Minimum

  `1`

Default

  `10`

Markup configuration example(s) :

    data-infinite-scroll-page-size='5'

### layout

layout: "list" | "card" | "table"

- Defined in ui/ResultList/ResultList.ts :259

Specifies the layout to use when displaying results in this `ResultList` (see Result Layouts). Specifying a value for this option automatically populates a [`ResultLayout`]{@link ResultLayout} component with a switcher for the layout.

For example, if there are two `ResultList` components in the page, one with its `layout` set to `list` and the other with the same option set to `card`, then the `ResultLayout` component will render two buttons respectively entitled List and Card.

See the `ValidLayout` type for the list of possible values.

Required

  Specifying a value for this option is required for the component to work

Default

  `list`

Markup configuration example(s) :

    data-layout='card'

### resultsContainer

resultsContainer: HTMLElement

- Defined in ui/ResultList/ResultList.ts :120

The element inside which to insert the rendered result templates.

Performing a new query clears the content of this element.

You can change the container by specifying its selector (e.g., `data-result-container-selector='#someCssSelector'`).

If you specify no value for this option, a `div` element will be dynamically created and appended to the result list. This element will then be used as a result container.

### waitAnimation

waitAnimation: "fade" | "spinner" | "none"

- Defined in ui/ResultList/ResultList.ts :135

The type of animation to display while waiting for a query to return.

The possible values are:

- `fade`: Fades out the current list of results while the query is executing.
- `spinner`: Shows a spinning animation while the query is executing.
- `none`: Use no animation during queries.

See also the `waitAnimationContainer` option.

Default

  `none`

Markup configuration example(s) :

    data-wait-animation='spinner'

### waitAnimationContainer

waitAnimationContainer: HTMLElement

- Defined in ui/ResultList/ResultList.ts :145

The element inside which to display the `waitAnimation`.

You can change this by specifying a CSS selector (e.g., `data-wait-animation-container-selector='#someCssSelector'`).

Defaults to the value of the `resultsContainer` option.

## Constructors

### constructor

- new ResultList(element: HTMLElement, options?: IResultListOptions, bindings?: IComponentBindings, elementClassId?: string): ResultList

- Overwrites Component.constructor

  - Defined in ui/ResultList/ResultList.ts :293

  Creates a new `ResultList` component. Binds various event related to queries (e.g., on querySuccess -> renderResults). Binds scroll event if the `enableInfiniteScroll` option is `true`.

  #### Parameters

  - ##### element: HTMLElement

    The HTMLElement on which to instantiate the component.

  - ##### Optional options: IResultListOptions

    The options for the `ResultList` component.

  - ##### Optional bindings: IComponentBindings

    The bindings that the component requires to function normally. If not set, these will be automatically resolved (with a slower execution time).

  - ##### Default value elementClassId: string = ResultList.ID

    The class that this component should instantiate. Components that extend the base ResultList use this. Default value is `CoveoResultList`.

  #### Returns ResultList
