How to set deafult value of django form select field in template?

To set the default value of a Django form select field, you can use the selected attribute of the <option> tag in the template. For example, if you have a form field called country and you want to set the default value to "United States", you can use the following code in the template:

<select name="country">
    <option value="United States" selected>United States</option>
    <option value="Canada">Canada</option>
    <option value="Mexico">Mexico</option>
    <!-- more options here -->
</select>

Alternatively, you can use the initial attribute of the form field to set the default value in the form's __init__ method. For example:

class MyForm(forms.Form):
    country = forms.ChoiceField(choices=COUNTRY_CHOICES, initial="United States")

Then in the template, you can simply use the {{ form.country }} to render the form field. The default value will be automatically set to "United States".

Simply you can do this way:

<select id="ip_addr">
    {% for host in hosts %}
        <option value="{{ host.ipaddress }}" {% if forloop.first %}selected{% endif %}>{{ host.ipaddress }}</option> #here default value will be first value from for loop
    {% endfor %}
</select>

This is the way you can do
