There are times when a PageBuilder Editor user would like to add a gallery to a block without having to leave the context of PageBuilder Editor to find and select the video they would like to add A common way to enable this functionality is to create a custom field that allows the user to enter a gallery ID or gallery canonical URL. However, it can be burdensome to search in Photo Center and then copy/paste the ID or URL back into the custom field.

A convenient way to integrate the search with Photo Center’s galleries is to use the [searchableField](https://dev.arcxp.com/pagebuilder-engine/developer-docs/consumer-api#searchablefield-function) hook. This hook can be applied to block elements to tell the PageBuilder Editor that users should be able to search Photo Center for a replacement gallery.

## Creating a Searchable Gallery

The Photo Center’s galleries search functionality is enabled whenever a Gallery block element uses the [searchableField](https://dev.arcxp.com/pagebuilder-engine/developer-docs/consumer-api#searchablefield-function) hook to override custom field values. Let’s first define a sample component that uses `searchableField`.

The component’s root element must include a style of position: relative for proper button placement in the Editor UI.

### Requirements

- Ensure your bundle has `@arc-fusion/cli` that’s version 2.0.9 or higher.

### Custom block example

The following example will produce a block level selection that will appear as custom fields with a dedicated “Select Gallery” button. This is useful if you plan to use multiple content sources for handling various different types of video functionality. This also allows you to select the content source you wish to use.

/components/features/global/gallery-integration-player-cs.jsx

```js
import PropTypes from 'prop-types'
import React from 'react'
import { useContent, useEditableContent } from 'fusion:content'

const GalleryIntegrationCs = ({ customFields }) => {
  const { searchableField } = useEditableContent()
  const { _id } = customFields
  const { contentService, contentConfigValues } = _id

  const content = useContent({
    source: contentService,
    key: {
      _id: contentConfigValues?._id,
      published: true
    }
  })

  if (!content) return null

  const gallery = content?.promo_items?.basic?.additional_properties

  return (
    <div
      className="feature-listing flex"
      {...searchableField('_id', 'gallery', { contentSource: 'galleries' })}>
      <img src={gallery?.originalUrl} width="560" height="315" alt={gallery?.originalName} />
    </div>
  )
}

GalleryIntegrationCs.propTypes = {
  customFields: PropTypes.shape({
    _id: PropTypes.contentConfig('feeds').tag({
      name: 'Schema'
    })
  })
}

GalleryIntegrationCs.label = {
  en: 'Gallery Search - Content Source'
}

GalleryIntegrationCs.icon = 'layout-column'

export default GalleryIntegrationCs
```

The values for the [searchableField](https://dev.arcxp.com/pagebuilder-engine/developer-docs/consumer-api#searchablefield-function) component hook maps to the following:

- **Param 1**: This maps to the component’s custom field ID associated with the contentConfig.
- **Param 2**: The type of content integration to associate with the contentConfig. In this case the value `gallery` will allow the component to show the gallery search integration.
- **Param 3**: An object, which at this time only takes a `contentSource` prop. The value should be the name of the content source for the editor preview to display the story.

### Content source example

This feature applies the [searchableField](https://dev.arcxp.com/pagebuilder-engine/developer-docs/consumer-api#searchablefield-function) hook to a top level component, which allows the PageBuilder Editor to replace the desired custom fields with the content provided by the [Content API](https://dev.arcxp.com/api/public-content-retrieval/content-api/). The input to the `searchableField` hook is an Object that contains a mapping of custom fields to the desired values from Photo Center’s galleries. In this example, when a gallery is selected, the gallery `_id` custom field will be replaced with the value of the gallery’s ID.

/content/sources/story-search.js

```js
const resolve = function resolve(key) {
  const website = key['arc-site'] || 'islands'
  const _id = key['_id']
  return `/content/v4/galleries/?_id=${_id}&website=${website}`
}

module.exports = {
  resolve,
  schemaName: 'feeds',
  params: {
    _id: 'text',
    canonical_url: 'text'
  },
  searchable: 'gallery'
}
```
