Usage of if judgment in HTML

In the process of Django web development, when writing HTML, a list variable with the same name is passed from the backend, but the content format is different and needs to be judged separately. I have consulted many articles and tried several methods, but the format seems to be wrong (I have not systematically studied the front end, and basically just copied it)
Later I found the usage of html if in Django framework

The format is roughly as follows

  <div class="if/else">
                    {% if formname == 'Callrecords' %}
                        Callrecords
                    {% elif formname == 'Riderecords' %}
                        Riderecords
                    {% elif formname == 'Clubinfo' %}
                        Clubinfo
                    {% elif formname == 'Clubmemb' %}
                        Clubmemb
                    {% elif formname == 'Personinfo' %}
                        Personinfo
                    {% endif %}
                    </div>

This syntax is provided by Django and is used in native HTML code writing but is useless. The code box above uses the HTML format, but you can also see that the content between the <div> tags cannot be marked by the HTML language, indicating that it is not a built-in HTML syntax.
But at least my Django project has no problem using it!

Summarize

The above is the usage of if judgment in HTML introduced by the editor. I hope it will be helpful to everyone. If you have any questions, please leave me a message and the editor will reply to you in time!
