django form dropdown list of numbers

You're looking for a ChoiceField which renders as a select html element by default.https://docs.djangoproject.com/en/dev/ref/forms/fields/#choicefield

class CronForm(forms.Form):    days = forms.ChoiceField(choices=[(x, x) for x in range(1, 32)])

you can start by choosing to render the fields manualy.A simple example:-

{% for field in form %}        <div class="fieldWrapper">            {{ field.errors }}            {{ field.label_tag }} {{ field }}            {% if field.help_text %}                <p class="help">{{ field.help_text|safe }}</p>            {% endif %}        </div>    {% endfor %}

This will render the form without any styling then you have to apply the relevent class to create a drop down list(copied from w3c dropdown css):-

 <div class="dropdown">    <button class="btn btn-default dropdown-toggle" type="button" id="menu1" data-toggle="dropdown">Tutorials    <span class="caret"></span></button>    <ul class="dropdown-menu" role="menu" aria-labelledby="menu1">      <li role="presentation"><a role="menuitem" tabindex="-1" href="#">HTML</a></li>      <li role="presentation"><a role="menuitem" tabindex="-1" href="#">CSS</a></li>      <li role="presentation"><a role="menuitem" tabindex="-1" href="#">JavaScript</a></li>      <li role="presentation" class="divider"></li>      <li role="presentation"><a role="menuitem" tabindex="-1" href="#">About Us</a></li>    </ul>  </div></div>

combining the two :-

<div class="dropdown">        <button class="btn btn-default dropdown-toggle" type="button" id="menu1" data-toggle="dropdown">Days            <span class="caret"></span></button>        <div class="fieldWrapper">            <ul class="dropdown-menu" role="menu" aria-labelledby="menu1">                {% for field in form %}                    <li class="fieldWrapper">                        {{ field.errors }}                        {{ field.label_tag }} {{ field }}                        {% if field.help_text %}                            <p class="help">{{ field.help_text|safe }}</p>                        {% endif %}                    </li>                {% endfor %}            </ul>        </div>    </div>
