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.
  • separate pages of content on basis of category

Usage

Basic Usage

Copy 
<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.

Copy 
<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.

Copy 
<TabDataList
    {...props}
    showCount
/>

Usage With All Props

Copy 
<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',
		},
	]}
    showCount={true}
    showRadio={true}
    showSearch={true}
    displayAsVertical={true}
	placeholder="Filter meetups"
	defaultValue="Social"
	URLParams={false}
/>

Props

  • componentId String unique identifier of the component, can be referenced in other components' react prop.
  • dataField String data field to be connected to the component's UI view.
  • data Object Array collection of UI labels with associated value to be matched against the database field.
  • title String or JSX [optional] title of the component to be shown in the UI.
  • placeholder String [optional] placeholder to be displayed in the searchbox. Defaults to "Search". Applicable only when showSearch is true.
  • defaultValue string [optional] selects an initial item from the list on mount.
  • value string [optional] 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.
  • showCount Boolean [optional] show a count of the number of occurences besides each list item. Defaults to false.
  • displayAsVertical Boolean [optional] layout tabs for the list vertically instead of horizontally.
  • showSearch Boolean [optional] Filter tabs using a search bar
  • showRadio Boolean [optional] show radio buttons with tabs just as we are using a SingleDataList
  • URLParams Boolean [optional] 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 Function [optional] customize the rendered list via a function which receives the item label, count & isSelected and expects a JSX or String back. For example:
    Copy 
    renderItem={(label, count, isSelected) => (
    <div>
        {label}
        <span style={{
            marginLeft: 5, color: isSelected ? 'red' : 'dodgerblue'
        }}>
            {count}
        </span>
    </div>
)}
  • render Function [optional] 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.
Copy 
<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

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

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,
Copy 
<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 String CSS class to be injected on the component container.

  • style Object CSS styles to be applied to the TabDataList component.

  • customQuery Function 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 Function 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 String [optional] 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.

    Note: This only works when enableAppbase prop is set to true in ReactiveBase.
