A facet is a list of values for a certain field occurring in the results, ordered using a configurable criteria (for example, number of occurrences). An atomic-color-facet displays a facet of the results for the current query as colors.

Introduction

A facet allows users to drill down inside a result set by filtering the result to certain field values. A Color Facet presents its information in a visual way.

User Experience and Best Practices

Usage Notes

  • A color facet is best for placing emphasis on the visual aspect of a facet value.

  • The two available options to display the facet values are box and checkbox.

    • The box display option will present the facet values in a grid with a larger tile format.

    • The checkbox display option will present the values in a list with a smaller icon or color tile.

Guidelines

When the facet doesn’t have too many values to display and the text labels are short, it’s best practice to use the box display option.

When using an image instead of a color tile or icon, it’s best practice to use the box display.

Use Cases and Examples

In commerce, a user shopping for a t-shirt can select the colors they want using a color-faceted.

Properties

Property Attribute Description Type Default

allowedValues

allowed-values

Specifies an explicit list of allowedValues in the Search API request. This list is in the form of a JSON string.

If you specify a list of values for this option, the facet only uses these values (if they are available in the current result set).

Example:

The following facet only uses the Contact, Account, and File values of the objecttype field. Even if the current result set contains other objecttype values, such as Message or Product, the facet does not use them.

<atomic-color-facet field="objecttype" allowed-values='["Contact","Account","File"]'></atomic-color-facet>

The maximum amount of allowed values is 25.

The default value is undefined, and the facet uses all available values for its field in the current result set.

string | string[]

'[]'

customSort

custom-sort

Identifies the facet values that must appear at the top, in this order. This parameter can be used in conjunction with the sortCriteria parameter.

Facet values not part of the customSort list will be sorted according to the sortCriteria.

Example:

The following facet will sort the Contact, Account, and File values at the top of the list for the objecttype field.

If there are more than these 3 values available, the rest of the list will be sorted using occurrences.

<atomic-color-facet field="objecttype" custom-sort='["Contact","Account","File"]' sort-criteria='occurrences'></atomic-color-facet>

The maximum amount of custom sort values is 25.

The default value is undefined, and the facet values will be sorted using only the sortCriteria.

string | string[]

'[]'

dependsOn

<atomic-facet facet-id="abc" field="objecttype" ...></atomic-facet>

<!-- To show the facet when any value is selected in the facet with id "abc": -->
<atomic-color-facet
  depends-on-abc
  ...
></atomic-color-facet>

<!-- To show the facet when value "doc" is selected in the facet with id "abc": -->
