<!-- Sample html file that corresponds to the 99-sample.js file              -->
<!-- This creates and configures the onscreen elements of the node           -->

<!-- If you use this as a template, update the copyright with your own name. -->

<!-- First, the content of the edit dialog is defined.                       -->

<script type="text/x-red" data-template-name="sample">
   <!-- data-template-name identifies the node type this is for              -->

   <!-- Each of the following divs creates a field in the edit dialog.       -->
   <!-- Generally, there should be an input for each property of the node.   -->
   <!-- The for and id attributes identify the corresponding property        -->
   <!-- (with the 'node-input-' prefix).                                     -->
   <!-- The available icon classes are defined Font Awesome Icons (FA Icons) -->

        <input type="text" id="node-input-topic" placeholder="Topic">
    </div>

   <p>Simple sample input node. Just sends a single message when it starts up.
   This is not very useful.</p>
   <p>Outputs an object called <code>msg</code> containing <code>msg.topic</code> and
   <code>msg.payload</code>. msg.payload is a String.</p>

<!-- Finally, the node type is registered along with all of its properties   -->
<!-- The example below shows a small subset of the properties that can be set-->
