Counted Tabs

The Counted Tabs component appends to each tab its respective count of results and offers the option to hide tabs that have no content.

Disclaimer: This component was built by the community at large and is not an official Coveo JSUI Component. Use this component at your own risk.

Getting Started

Testing the Component

For quick testing, you can add the script from unpkg:

<script src="https://unpkg.com/@coveops/counted-tabs@latest/dist/index.min.js"></script>

Disclaimer: Unpkg should be used for testing but not for production.

Using the Component

1. Install the component into your project.

   npm i @coveops/counted-tabs

2. Use the component or extend it:

   Typescript

   import { CountedTabs, ICountedTabsOptions } from '@coveops/counted-tabs';

   Javascript

   const CountedTabs = require('@coveops/counted-tabs').CountedTabs;

3. You can also expose the component alongside other components being built in your project.

   export * from '@coveops/counted-tabs'

4. Include the component in your template as follows:

   Place the component after the last tab in the coveo-tab-section.

   <div class="CoveoCountedTabs" data-field="@commontabs"></div>

Coveo Pipelines Configuration

In order for this component to work as expected, some changes will be necessary in your pipelines configuration on the Coveo Platform.

Fields

A commontabs field needs to be added as a Multi-Value Facet. For more information on adding a field, you can start with this reference: Adding and Managing Fields.

Sources

On each source displaying content in tabs, under manage mappings, add a semi-colon-separated list of all tab ids (as per your UI) that a given resource can see. For more information on mapping rules in Coveo, you can start with this reference: Adding and Managing Source Mappings.

In more complex situations, it may be necessary to add the commontabs field on a per-document basis, in which case a new post-conversion extension will be necessary. You can get started with your Extension Script with this documentation reference: Coveo Cloud V2 Indexing Pipeline Extensions.

Options

The following options can be configured:

| Option | Required | Type | Default | Notes | | --- | --- | --- | --- | --- | | field | Yes | string | | The custom field added to all sources to normalize the tabs | | defaultTab | No | string | All | The id of the default designated default CoveoTab | | hideWhenEmpty | No | boolean | true | Hides a tab when the count of its items is 0 | | countTemplate | No | string | ${count} | Applies basic formatting to the count value. For complex changes that require using html markup, see the formatCount method |

Extending

Extending the component can be done as follows:

import { CountedTabs, ICountedTabsOptions } from "@coveops/counted-tabs";

export interface IExtendedCountedTabsOptions extends ICountedTabsOptions {}

export class ExtendedCountedTabs extends CountedTabs {
    protected shouldHideTab(tab: HTMLElement, defaultTabNbRes: number): boolean {
        return shouldHide;
    }
}

The following methods can be extended to provide additional functionalities or handle more complex use cases.

shouldHideTab

protected shouldHideTab(tab: HTMLElement, defaultTabNbRes: number): boolean {}

The shouldHideTab method defines the logic used to hide the tab based on the id and counts.

formatCount

protected formatCount(count)

The formatCount method injects the count value for a given tab into the specified countTemplate. The value returned here will be shown as the count in the template.

getCountElement

protected getCountElement(nbRes): HTMLElement 

The getCountElement method returns the DOM element that will contain the formatted count.
