How to pass value from drop down list to view in template?

Question

Django

In the template, so far I have built such a design

<form action="{% url 'cv'  format_='???????' %}" method="post">
               <fieldset>
                <select class="form-control custom-select-main mx-auto" >
                  <option value="json">json</option>
                  <option value="html">html</option>
                  <option value="docx">docx</option>
                </select>
               </fieldset>
</form>
                <a class="btn btn-success" href="{% url 'cv'  format=???????? %}">Get CV</a

Now the page displays a button and a drop-down box with 3 options, but I don’t understand how to transfer the selected option to the view as a format value.
Can you please tell me how to implement this functionality?

Great way without creating forms

<div id="selector">
    <select>
        <option value="#">Download</option>
        <option value="{% url 'cv'  format_='docx' %}">DOCX</option>
        <option value="{% url 'cv'  format_='json' %}">JSON</option>
        <option value="{% url 'cv'  format_='html' %}">HTML</option>
    </select>
</div>

<script>
    $(function(){
        // bind change event to select
        $('#selector select').bind('change', function () {
            var url = $(this).val(); // get selected value
            if (url) { // require a URL
                window.location = url; // redirect
            }
            return false;
         });
     });
 </script>

Assign an action to the form with the required url, add name="format" to the select and put the button into the form. No js is needed here.
Learn to work with forms, and not write crutches, which you will understand later.
