Refinement Lists
Overview
This component provides a set of tools to filter the results using different filters. If the user selects a combination of filters, the search will be updated with it.
To use this component, you need to use Filter components to create the different filter types. Besides, this component must be linked to a search Store, since it retrieves the values of the last search results to filter.
Usage
This is how you create this component:
sdk.component('refinement-lists', target: HTMLElement|String, options: Object);Sample
By default, this component looks like this with a facet filter:

Examples
Basic example using the results component Store, through the linkTo method:
<div id="colour-filters"></div>
<div id="results"></div>
<script>
var results = sdk.component('results', '#results');
var colorRefinement = sdk.filterComponent('facet', { attributeName: 'COLOUR'});
var colorFilter = sdk.component('refinement-lists', '#colour-filters', {
refinements: [
{
headerText: 'Colour Filter',
component: colorRefinement
}
]
});
results.linkTo(colorFilter);
</script>
Example using templates
<div id="colour-filters"></div>
<div id="results"></div>
<script>
var results = sdk.component('results', '#results');
var colorRefinement = sdk.filterComponent('facet', { attributeName: 'COLOUR'});
var colorFilter = sdk.component('refinement-lists', '#colour-filters', {
templates: {
item: '<span>{{ name }}</span> ({{ count }})',
// or
item: function (facet) {
return '<span>' + facet.value + '</span> (' + facet.count + ')';
}
},
refinements: [
{
headerText: 'Colour Filter',
component: colorRefinement
}
