<script type="text/html" data-help-name="input-topic">
    <p>A node that changes the topic of incoming messages while preserving their payload and other properties.</p>

    <h3>Inputs</h3>
    <dl class="message-properties">
        <dt>payload <span class="property-type">any</span></dt>
        <dd>Any input payload (passed through unchanged)</dd>
        
        <dt>topic <span class="property-type">string</span></dt>
        <dd>Input topic (will be replaced with configured topic)</dd>
        
        <dt>other properties</dt>
        <dd>All other message properties are preserved</dd>
    </dl>

    <h3>Outputs</h3>
    <dl class="message-properties">
        <dt>payload <span class="property-type">any</span></dt>
        <dd>Same as input payload (unchanged)</dd>
        
        <dt>topic <span class="property-type">string</span></dt>
        <dd>The configured topic name</dd>
        
        <dt>__srcid <span class="property-type">string</span></dt>
        <dd>The node's identifier</dd>
        
        <dt>other properties</dt>
        <dd>All other input message properties are preserved</dd>
    </dl>

    <h3>Configuration</h3>
    <dl class="message-properties">
        <dt>Name <span class="property-type">string</span></dt>
        <dd>Optional name to identify the node in the flow</dd>
        
        <dt>Topic <span class="property-type">string</span></dt>
        <dd>The topic to assign to outgoing messages</dd>
    </dl>

    <h3>Status</h3>
    <dl class="message-properties">
        <dt>Grey dot</dt>
        <dd>Shows the configured topic name</dd>
    </dl>

    <h3>Details</h3>
    <p>This node is useful for message routing and topic management in flows. Common use cases include:</p>

    <h4>Use Cases</h4>
    <ul>
        <li>Routing messages to specific flow branches based on topic</li>
        <li>Standardizing topics from different sources</li>
        <li>Creating topic hierarchies</li>
        <li>Preparing messages for specific node requirements</li>
    </ul>

    <h4>Operation</h4>
    <p>The node:</p>
    <ul>
        <li>Preserves all input message properties</li>
        <li>Replaces the topic with the configured value</li>
        <li>Adds a source identifier (__srcid)</li>
        <li>Passes the message immediately (no delay)</li>
    </ul>

    <p>This node is particularly useful when working with nodes that rely on specific topic patterns or when organizing message flows in larger systems.</p>
