<p>A component is a single building block within a flow. It consists of inputs, outputs, and parameters that define their functionality. These elements provide a convenient and straightforward way to compose LLM-based applications. Learn more about components and how they work below.</p>
<p>During the flow creation process, you will notice handles (colored circles) attached to one or both sides of a component. These handles use distinct colors to indicate the types of inputs and outputs that can be interconnected. Hover over a handle to see connection details.</p>

<p>On the top right corner of the component, you&#x27;ll find the a play button to run a component. Once it runs, a status icon appears and you can hover over that to visualize success or error messages. Start interacting with your AI by clicking the <strong>Playground</strong> at the bottom right of the workspace.</p>

<p>Each component is unique, but they all have a menu bar at the top that looks something like this.</p>

<p>It consists of options such as:</p>
<ul>
<li><strong>Code</strong> — displays the component&#x27;s Python code. You can modify the code and save it.</li>
<li><strong>Advanced</strong> — See and adjust all parameters of a component.</li>
<li><strong>Freeze</strong> — After a component runs, lock its previous output state to prevent it from re-running.</li>
</ul>
<p>Click <strong>All</strong> (the &quot;...&quot; button) to see all options.</p>

<p>Langflow includes an output visualizer for components that opens a pop-up screen. This allows you to easily inspect and monitor transmissions between components, providing instant feedback on your workflows.</p>

<p>Langflow components can be edited by clicking the <strong>Advanced Settings</strong> button.</p>
<p>Hide parameters with the <strong>Show</strong> button to reduce complexity and keep the workspace clean and intuitive for experimentation.</p>
<p>You can also double-click a component&#x27;s name and description to modify those. Component descriptions accept markdown syntax.</p>
<h3 class="anchor anchorWithHideOnScrollNavbar_WYt5" id="c3f5ed818e3b40ceb6534dc358e1a5f2">Group Components<a class="hash-link" aria-label="Direct link to Group Components" title="Direct link to Group Components" href="/components#c3f5ed818e3b40ceb6534dc358e1a5f2"></a></h3>
<p>Multiple components can be grouped into a single component for reuse. This is useful when combining large flows into single components (like RAG with a vector database, for example) and saving space.</p>
<ol>
<li>Hold <strong>Shift</strong> and drag to select components.</li>
<li>Select <strong>Group</strong>.</li>
<li>The components merge into a single component.</li>
<li>Double-click the name and description to change them.</li>
<li>Save your grouped component to in the sidebar for later use!</li>
</ol>

<p>A component&#x27;s state is stored in a database, while sidebar components are like starter templates. As soon as you drag a component from the sidebar to the workspace, the two components are no longer in parity.</p>
<p>The component will keep the version number it was initialized to the workspace with. Click the <strong>Update Component</strong> icon (exclamation mark) to bring the component up to the <code>latest</code> version. This will change the code of the component in place so you can validate that the component was updated by checking its Python code before and after updating it.</p>
