On the attribute edition page in Magento back-office (Store > Attributes > Product), following parameters can be modified on the Storefront Properties tab :

You can refer to the following section to enhance the faceting configuration.

Each product attribute can also be configured when it is used as a facet in the search results and/or category view page.

On the attribute edition page in Magento back-office, following parameters can be modified :

Parameter	Default value	Description
Facet coverage rate	90	The minimum coverage rates of results by this attribute. Example, if set to 90% on the "Brand" attribute, the facet will be displayed only if 90% of the products in the search results or category have a brand.

Facet sort order	Result count	This is how the facet values will be ordered. Result count : Will order values according to their number of results (descending). Admin sort : Values will be displayed as ordered in attribute's options values in Magento back-office. Name : Values will be displayed alphabetically (ascending).

ElasticSuite allows you to display custom attributes of yours with Sliders (like the Price).

There are some prerequisites to respect for this point to work :

• your attribute values must be exclusively digits
• you must specify that your attribute is using "Decimal Number" as imput validation, or "price" as input type.

Let's see a quick how-to for a new attribute.

This attribute will be Temperature and we plan to display a slider of values in Celsius degrees.

Let's go to Stores > Product > Attributes and create a new One.

I call it "Temperature", set its code to "temperature" and the input as a text field.

Then I set the "Input validation" to "Decimal Number"

Next step is to configure the attribute for being filterable in layered navigation and/or in search. See the steps describe above to perform this.

Once you are done, you can click on Save and Continue Edit and go back to the StoreFront properties.

You will then see a new fieldset named Slider Display Configuration

In this fieldset you can configure the display of your newly created attribute :

Parameter	Default value	Description
Display pattern		In this field you should enter the pattern for your Slider. "%s" represents the value. So if you type "%s °C" you will obtain something like : "20 °C".
Display precision	0	The number of digits to show for precision when filtering. Let this field to 0 to have a slider displaying integer values.

Once you are done, you can now populate this attribute values for your products. Then all you will have to do is to process a full reindex.

The slider should now be displayed in the Front-Office :
