Interactive Elements Library

1. Tabs Component

When to use: Comparing 2-5 options or variants

HTML structure required:

<div class="tab-container" role="tablist">
    <button role="tab" aria-selected="true" id="tab-1">Option A</button>
    <button role="tab" id="tab-2">Option B</button>
</div>
<div class="tab-panels">
    <div role="tabpanel" id="panel-1" aria-labelledby="tab-1">
        [Content A]
    </div>
    <div role="tabpanel" id="panel-2" aria-labelledby="tab-2" hidden>
        [Content B]
    </div>
</div>

JavaScript implementation:

function initTabs() {
    const tabContainers = document.querySelectorAll('.tab-container');

    tabContainers.forEach(container => {
        const tabs = container.querySelectorAll('[role="tab"]');
        const panelsContainer = container.nextElementSibling;
        const panels = panelsContainer.querySelectorAll('[role="tabpanel"]');

        tabs.forEach((tab, index) => {
            tab.addEventListener('click', () => {
                // Deselect all tabs
                tabs.forEach(t => t.setAttribute('aria-selected', 'false'));
                // Hide all panels
                panels.forEach(p => p.hidden = true);

                // Select clicked tab and show its panel
                tab.setAttribute('aria-selected', 'true');
                panels[index].hidden = false;
            });

            // Keyboard navigation
            tab.addEventListener('keydown', (e) => {
                if (e.key === 'ArrowRight') {
                    const nextTab = tabs[(index + 1) % tabs.length];
                    nextTab.click();
                    nextTab.focus();
                } else if (e.key === 'ArrowLeft') {
                    const prevTab = tabs[(index - 1 + tabs.length) % tabs.length];
                    prevTab.click();
                    prevTab.focus();
                }
            });
        });
    });
}
