TabDataList

TabDataList creates a tabbed list UI component. It is used for filtering results based on the current selection from a list of data items.

This component is similar to SingleDataList. It just renders a tab list instead of radio buttons incase of SingleDataList.

Example uses:

• select a category from a list of categories for filtering e-commerce search results.
• display result tabs based on a value classification

Usage

Basic Usage

<TabDataList
	componentId="MeetupTops"
	dataField="group.group_topics.topic_name_raw.raw"
	title="Meetups"
	data={[
		{
			label: 'Social',
			value: 'Social',
		},
		{
			label: 'Travel',
			value: 'Travel',
		},
		{
			label: 'Outdoors',
			value: 'Outdoors',
		},
	]}
/>

Render

as a vertical list We can pass the displayAsVertical to be true to render the list vertically.

<TabDataList
    {...props}
    displayAsVertical
/>

Show

no. of documents When we want to show the no. of documents for each category(tab) then we can pass showCount prop.

<TabDataList
    {...props}
    showCount
/>

Usage (with all props)

<TabDataList
	componentId="MeetupTops"
	dataField="group.group_topics.topic_name_raw.raw"
	title="Meetups"
	data={[
		{
			label: 'Social',
			value: 'Social',
		},
		{
			label: 'Travel',
			value: 'Travel',
		},
		{
			label: 'Outdoors',
			value: 'Outdoors',
		},
	]}
	selectAllLabel="All"
    showCount={true}
    showRadio={true}
    showSearch={true}
    displayAsVertical={true}
	placeholder="Filter meetups"
	defaultValue="Social"
    selectAllLabel="All meetups"
	URLParams={false}
    endpoint={{
      url:"https://appbase-demo-ansible-abxiydt-arc.searchbase.io/recipes-demo/_reactivesearch.v3", //mandatory
      headers:{
        // relevant headers
      },
      method: 'POST'
    }}        
/>

Props

componentId

unique identifier of the component, can be referenced in other components' react prop.

compoundClause

Configure whether the DSL query is generated with the compound clause of must or filter. If nothing is passed the default is to use must. Setting the compound clause to filter allows search engine to cache and allows for higher throughput in cases where scoring isn’t relevant (e.g. term, geo or range type of queries that act as filters on the data)

This property only has an effect when the search engine is either elasticsearch or opensearch.

Note: compoundClause is supported with v8.16.0 (server) as well as with serverless search.

endpoint

endpoint prop provides the ability to query a user-defined backend service for this component, overriding the data endpoint configured in the ReactiveBase component. Accepts the following properties:

• url String [Required] URL where the data cluster is hosted.
• headers Object [optional]
  set custom headers to be sent with each server request as key/value pairs.
• method String [optional]
  set method of the API request.
• body Object [optional]
  request body of the API request. When body isn't set and method is POST, the request body is set based on the component's configured props.

• Overrides the endpoint property defined in ReactiveBase.
• If required, use transformResponse prop to transform response in component-consumable format.

dataField

data field to be connected to the component's UI view.

data

collection of UI labels with associated value to be matched against the database field.

title

title of the component to be shown in the UI.

placeholder

placeholder to be displayed in the searchbox. Defaults to "Search". Applicable only when showSearch is true.

defaultValue

selects an initial item from the list on mount.

value

controls the current value of the component. It selects the item from the list (on mount and on update). Use this prop in conjunction with onChange function.

selectAllLabel

if provided displays an additional option to select all list values.

showCount

show a count of the number of occurences besides each list item. Defaults to false.

displayAsVertical

layout tabs vertically. Defaults to false.

showSearch

filter tabs using a search bar

showRadio

show radio buttons just as we are using a SingleDataList

selectAllLabel

If set, an additional option to select all the values is displayed

URLParams

enable creating a URL query string parameter based on the selected value of the list. This is useful for sharing URLs with the component state. Defaults to false.

renderItem

customize the rendered list via a function which receives the item label, count & isSelected and expects a JSX or String back. For example:

renderItem={(label, count, isSelected) => (
    <div>
        {label}
        <span style={{
            marginLeft: 5, color: isSelected ? 'red' : 'dodgerblue'
        }}>
            {count}
        </span>
    </div>
)}

render

an alternative callback function to renderItem, where user can define how to render the view based on all the data changes.

It accepts an object with these properties:

• data: array An array of results obtained from the applied query.
• rawData object An object of raw response as-is from elasticsearch query.
• value: string current selected value.
• handleChange: function A callback function can be used to mark the list value as selected.

<TabDataList
	render={({ data, handleChange }) =>
		data.map(item => (
			<div onClick={() => handleChange(item.key)} key={item.key}>
				<span>{item.key}</span>
				<span>{item.doc_count}</span>
			</div>
		))
	}
/>

Or you can also use render function as children

<TabDataList>
        {
            ({
                data,
                value,
                handleChange,
            }) => (
                // return UI to be rendered
            )
        }
</TabDataList>

Demo

Extending

TabDataList component can be extended to

1. customize the look and feel with className, style,
2. update the underlying DB query with customQuery, defaultQuery,

<TabDataList
  ...
  className="custom-class"
  style={{"paddingBottom": "10px"}}
  defaultQuery={
    function(value, props) {
      return {
        timeout: "1s"
      }
    }
  }
  customQuery={
    function(value, props) {
      return {
        query: {
            match: {
                data_field: "this is a test"
            }
        }
      }
    }
  }
/>

className

CSS class to be injected on the component container.

style

CSS styles to be applied to the TabDataList component.

customQuery

takes value and props as parameters and returns the data query to be applied to the component, as defined in Elasticsearch Query DSL. Note: customQuery is called on value changes in the TabDataList component as long as the component is a part of react dependency of at least one other component.

defaultQuery

takes value and props as parameters and returns the data query to be applied to the source component, as defined in Elasticsearch Query DSL, which doesn't get leaked to other components. Read more about it here.

index

The index prop can be used to explicitly specify an index to query against for this component. It is suitable for use-cases where you want to fetch results from more than one index in a single ReactiveSearch API request. The default value for the index is set to the app prop defined in the ReactiveBase component.
