Example : Shorter Size Selector Options

Logic

Format the size selector to only display size options

JS Code:

customization.js

function hooks() {
    // before: XL (8-9) => after: XL
    window.SerpOptions.registerHook("format-serp-size-variant-selector-options", (item) => {
        return item.split(" (")[0];
    });
}
// execution here
if (window.SerpOptions) {
    hooks();
} else {
    window.addEventListener('fast-serp-ready', function () {
        hooks();
    });
}
