Visual Discovery Configuration Options

Configure the Visual Discovery widget by setting options on window.__fast_options before the widget loads.

Configuration Structure

Options are set globally on the window object and merged into the widget configuration:

window.__fast_options = {
    // Button customization
    discovery_button_text: "Find Similar",
    similar_styles_button_text: "Shop Similar",
    similar_styles_button_color: "#000000",
    visual_discovery_button_color: "#000000",

    // Swatch configuration
    display_swatches_feature: true,
    hide_oos_swatches: true,
    color_attribute_names: ["Color", "colour"],
    swatch_width: 32,
    swatch_visibility_threshold: 0,

    // Mobile features
    display_add_to_cart_mobile: false,

    // Filter customization
    visualAttributesFilter: ["Color group", "Brand"],
    visualVariantsFiltersExcluded: ["Color"]

    // Advanced options
    disable_vd_shadow_root: true
};

Filter Options

Option	Type	Default	Description
visualAttributesFilter	string[]	[]	Product attribute names to use as filters (e.g., ["Color group", "Brand", "Material"]) - these are product-level attributes, not variant attributes
visualVariantsFiltersExcluded	string[]	[]	Variant filter names to exclude from display (e.g., ["Color", "Size"]) - useful when replacing with attribute filters

Advanced Options

Option	Type	Default	Description
disable_vd_shadow_root	boolean	false	Disable Shadow DOM encapsulation. When enabled, styles are injected into the document head instead of shadow root, allowing global CSS to affect the widget.

Shadow DOM Customization

By default, Visual Discovery uses Shadow DOM to encapsulate styles and prevent conflicts with the host page. However, this also prevents external CSS from styling the widget.

Option 1: Custom Styles with Shadow DOM (default)

Add a <style> tag with id="fs-visual-discovery-custom-styles" to your page. This will be cloned into the shadow root:

<style id="fs-visual-discovery-custom-styles">
    .modal-header.default {
        background: #f5f5f5;
    }
    .product-results-wrapper {
        padding: 20px;
    }
</style>

Option 2: Disable Shadow DOM

If you need full CSS control or have complex styling requirements:

window.__fast_options = {
    disable_vd_shadow_root: true
};

With this option enabled:

• Widget styles are added to document.head
• Global CSS can style the widget directly
• No need for the special id="fs-visual-discovery-custom-styles" workaround
