How to Build a Shadcn Sheet Component in React: Cart and Filter Panel Examples

<p>A Sheet is a panel that slides in from the edge of the screen instead of popping up in the center like a modal. You've likely used one when you've opened a shopping cart on an e-commerce site or tapped a filter icon and watched options slide in from the side.</p> <p>Building a Sheet that scrolls correctly with long content, keeps a header and footer fixed in place, and manages form or counter state without bugs takes more than wrapping a <code>&lt;div&gt;</code> in a slide animation.</p> <p>In this tutorial, you'll build two production-ready Sheet components using shadcn/ui and Base UI primitives via Shadcn Space:</p> <ol> <li><p>A <strong>Shopping Cart Sheet</strong> with quantity controls, item removal, and a live subtotal.</p> </li> <li><p>A <strong>Filter Panel Sheet</strong> with category checkboxes, a price range slider, star ratings, and an active filter count.</p> </li> </ol> <p>By the end, you'll have both components running in your project, and you'll understand the state and layout decisions behind them well enough to build your own Sheet variants from scratch.</p> <h2 id="heading-table-of-contents"><strong>Table of Contents</strong></h2> <ul> <li><p><a href="#heading-prerequisites">Prerequisites</a></p> </li> <li><p><a href="#heading-what-youll-build">What You'll Build</a></p> </li> <li><p><a href="#heading-how-to-set-up-the-cli-registry">How to Set Up the CLI Registry</a></p> </li> <li><p><a href="#heading-how-to-build-the-shopping-cart-sheet-sheet-03">How to Build the Shopping Cart Sheet (sheet-03)</a></p> </li> <li><p><a href="#heading-how-to-build-the-filter-panel-sheet-sheet-04">How to Build the Filter Panel Sheet (sheet-04)</a></p> </li> <li><p><a href="#heading-quick-reference-table">Quick Reference Table</a></p> </li> <li><p><a href="#heading-key-concepts-recap">Key Concepts Recap</a></p> </li> <li><p><a href="#heading-conclusion">Conclusion</a></p> </li> <li><p><a href="#heading-resources">Resources</a></p> </li> </ul> <h2 id="heading-prerequisites">Prerequisites</h2> <p>Before you start, make sure you have:</p> <ul> <li><p>Node.js 18 or higher installed</p> </li> <li><p>shadcn/ui initialized in your project (<code>npx shadcn@latest init</code>)</p> </li> <li><p>Basic knowledge of React and TypeScript</p> </li> </ul> <p>If you haven't initialized shadcn/ui yet, run <code>npx shadcn@latest init</code> in your project root and follow the prompts before continuing.</p> <h2 id="heading-what-youll-build">What You'll Build</h2> <p>This tutorial uses components installed through the <a href="https://shadcnspace.com/"><strong>Shadcn Space</strong></a> registry, an open-source collection of production-ready components and UI blocks for shadcn/ui.</p> <p>You can browse the full set in the <a href="https://shadcnspace.com/components/sheet"><strong>Shadcn Sheet component library</strong></a>. Each component supports both Radix UI and Base UI primitives and includes a <strong>Copy Prompt option</strong>, so you can paste the component spec into tools like v0, Lovable, or Bolt if you're prototyping.

Without this step, the install commands below will fail.</p> <p>For a full walkthrough of registry setup, see the <a href="https://shadcnspace.com/docs/getting-started/how-to-use-shadcn-cli"><strong>getting started guide</strong></a>. Shadcn Space also ships an <a href="https://shadcnspace.com/mcp"><strong>MCP server</strong></a>, so you can browse and install components straight from your editor if your workflow uses MCP tooling.

Derived totals instead of tracked state</h4> <p><code>subtotal</code> and <code>totalCount</code> are calculated from <code>items</code> on every render, not stored in their own <code>useState</code>. If you tracked them separately, they'd drift out of sync the first time you updated <code>items</code> and forgot to update the count alongside them.</p> <h4 id="heading-2-removing-an-item-is-just-zeroing-its-quantity">2. Removing an item is just zeroing its quantity</h4> <pre><code class="language-javascript">const updateQty = (id, delta) =&gt; { setItems((prev) =&gt; prev .map((item) =&gt; (item.id === id ? { ...item, qty: item.qty + delta } : item)) .filter((item) =&gt; item.qty &gt; 0) ); }; </code></pre> <p>The trash icon calls <code>updateQty(item.id, -item.qty)</code>, which drops that item's quantity to zero. The <code>.filter()</code> step then removes it from the array. This means you don't need a separate "remove item" function that duplicates logic already living in <code>updateQty</code>.</p> <h4 id="heading-3-render-prop-instead-of-aschild">3. <code>render</code> prop instead of <code>asChild</code></h4> <p><code>SheetTrigger</code> and <code>SheetClose</code> use the <code>render</code> prop (<code>render={&lt;Button ... /&gt;}</code>) rather than wrapping children in an <code>asChild</code> pattern. This is the Base UI convention that Shadcn Space components use, and it keeps the button's accessibility behavior (focus states, keyboard handling) entire instead of overriding it with a custom wrapper.</p> <h4 id="heading-4-fixed-header-and-footer-scrollable-middle">4. Fixed header and footer, scrollable middle</h4> <pre><code class="language-javascript">&lt;SheetContent className="flex flex-col p-0 gap-0"&gt; &lt;SheetHeader className="border-b" /&gt; &lt;div className="flex-1 overflow-y-auto"&gt;{/* items */}&lt;/div&gt; &lt;SheetFooter className="border-t" /&gt; &lt;/SheetContent&gt; </code></pre> <p><code>flex-1 overflow-y-auto</code> on the middle div is what keeps the header and footer fixed while the item list scrolls independently. Skip this, and a long cart pushes the checkout button off-screen.</p> <h3 id="heading-live-preview"><strong>Live Preview:</strong></h3> <img src="https://cdn.hashnode.com/uploads/covers/68b53a3d851476bd2ce87f12/dec70851-3b64-43d4-9611-f75165f7c4ca.gif" alt="dec70851-3b64-43d4-9611-f75165f7c4ca" style="display:block;margin:0 auto" width="1152" height="648" loading="lazy"> <h2 id="heading-how-to-build-the-filter-panel-sheet-sheet-04">How to Build the Filter Panel Sheet (sheet-04)</h2> <h3 id="heading-what-the-filter-sheet-does">What the Filter Sheet Does</h3> <p>The Filters button slides a panel in from the left with category checkboxes, a price range slider, a star rating filter, and an availability toggle.

Use a separate state for each filter type</h4> <p>Categories and availability use arrays because users can select multiple options. Rating stores a single value (or <code>null</code>) since only one rating can be selected. Price uses a two-value array (<code>[min, max]</code>) to store the selected range. This keeps each filter's state simple and matches how the UI works.</p> <h4 id="heading-2-activecount-is-computed-not-tracked">2. <code>activeCount</code> is computed, not tracked</h4> <p>Same reasoning as the cart badge above:</p> <pre><code class="language-javascript">const activeCount = selectedCategories.length + (priceRange[0] !== 0 || priceRange[1] !== 1000 ? 1 : 0) + (selectedRating !== null ? 1 : 0) + selectedAvailability.length; </code></pre> <p>If you tracked this count manually, you'd eventually add a new filter, forget to update the count logic, and end up with a badge that lies to the user.</p> <h4 id="heading-3-apply-filters-closes-the-panel-clear-all-doesnt">3. "Apply Filters" closes the panel, "Clear All" doesn't</h4> <p><code>Clear All</code> calls <code>clearAll()</code> directly on a plain <code>Button</code>. <code>Apply Filters</code> is wrapped in <code>SheetClose</code>, so it resets nothing but closes the panel. A user clearing filters usually wants to keep the panel open to pick new ones. Closing on every action would force them to reopen it each time.</p> <h4 id="heading-4-toggling-a-category-with-filter-and-spread">4. Toggling a category with <code>.filter()</code> and spread</h4> <pre><code class="language-javascript">const toggleCategory = (cat) =&gt; setSelectedCategories((prev) =&gt; (prev.includes(cat) ? prev.filter((c) =&gt; c !== cat) : [...prev, cat])); </code></pre> <p>This one line handles both adding and removing a category from the array, based on whether it's already present. It's a pattern worth reusing anywhere you have a multi-select checkbox list backed by an array of strings.</p> <h3 id="heading-live-preview"><strong>Live Preview:</strong></h3> <img src="https://cdn.hashnode.com/uploads/covers/68b53a3d851476bd2ce87f12/e3850372-c172-4d49-b973-09192e80bc61.gif" alt="e3850372-c172-4d49-b973-09192e80bc61" style="display:block;margin:0 auto" width="1152" height="648" loading="lazy"> <h2 id="heading-quick-reference-table">Quick Reference Table</h2> <table style="min-width:378px"><colgroup><col style="min-width:25px"><col style="width:80px"><col style="width:273px"></colgroup><tbody><tr><td><p><strong>Sheet</strong></p></td><td><p><strong>Identifier</strong></p></td><td><p><strong>Use Case</strong></p></td></tr><tr><td><p><strong>Shopping Cart Sheet</strong></p></td><td><p>sheet-03</p></td><td><p>Cart drawers, order summaries</p></td></tr><tr><td><p><strong>Filter Panel Sheet</strong></p></td><td><p>sheet-04</p></td><td><p>Product filters, search refinement panels</p></td></tr></tbody></table> <p>To install either, swap the identifier in the CLI command:</p> <pre><code class="language-javascript">npx shadcn@latest add @shadcn-space/&lt;identifier&gt; </code></pre> <hr> <h2 id="heading-key-concepts-for-using-shadcn-sheet">Key Concepts for Using Shadcn Sheet</h2> <ul> <li><p><strong>Use a Sheet for secondary workflows:</strong> It's ideal for filters, shopping carts, settings, navigation menus, and forms that shouldn't interrupt the main page.</p> </li> <li><p><strong>Keep the layout consistent:</strong> Use a fixed header, a scrollable content area (<code>flex-1 overflow-y-auto</code>), and a fixed footer so actions remain visible even with long content.</p> </li> <li><p><strong>Derive UI values from state:</strong> Counts, totals, and badges (such as active filters or cart items) should be calculated from state instead of being stored separately.</p> </li> <li><p><strong>Close the Sheet after completing an action:</strong> Actions like <strong>Apply Filters</strong>, <strong>Save</strong>, or <strong>Checkout</strong> should close the Sheet. Actions like <strong>Clear Filters</strong> or <strong>Reset</strong> should keep it open so users can continue making changes.</p> </li> <li><p><strong>Choose the right state structure:</strong> Use arrays for multi-select options (such as categories or availability), a single value (or <code>null</code>) for single-select options (such as ratings), and a two-value array (<code>[min, max]</code>) for range filters like price.</p> </li> <li><p><strong>Keep actions easy to reach:</strong> Place primary actions like <strong>Apply</strong>, <strong>Save</strong>, or <strong>Checkout</strong> in the footer so they remain accessible while the content scrolls.</p> </li> <li><p><strong>Avoid overloading the Sheet:</strong> If the workflow is long, requires multiple steps, or needs the user's full attention, consider using a dedicated page instead of a Sheet.</p> </li> </ul> <h2 id="heading-conclusion">Conclusion</h2> <p>In this guide, we built two practical Shadcn Sheet components, a shopping cart and a filter panel, to demonstrate the patterns you'll use most often in React applications.
