HTML5 introduces a support for {{{<datalist>}}} '''HTML5''' elements for
suggestions in '''input''' tag
To do this in Django currently, you have to do something like:
'''django/forms/widgets/datalist.html'''
{{{
{% include "django/forms/widgets/input.html" %}
<datalist id="{{ widget.id }}" name="{{ widget.name }}"{% include
"django/forms/widgets/attrs.html" %}>{% for group_name, group_choices,
group_index in widget.optgroups %}{% if group_name %}
<optgroup label="{{ group_name }}">{% endif %}{% for option in
group_choices %}
{% include option.template_name with widget=option %}{% endfor %}{% if
group_name %}
</optgroup>{% endif %}{% endfor %}
</datalist>
}}}
'''django/forms/widgets/datalist_option.html'''
{{{
<option value="{{ widget.value|stringformat:'s' }}"{% include
"django/forms/widgets/attrs.html" %}>
}}}
'''django/forms/widgets.py'''
{{{#!python
class Datalist(Select):
input_type = 'text'
template_name = 'django/forms/widgets/datalist.html'
option_template_name = 'django/forms/widgets/datalist_option.html'
add_id_index = False
checked_attribute = {'selected': True}
option_inherits_attrs = False
}}}
'''django/forms/fields.py'''
{{{#!python
class DatalistField(ChoiceField):
widget = Datalist
default_error_messages = {
'invalid_choice': _('Select a valid choice. %(value)s is not one
of the available choices.'),
}
def __init__(self, *, choices='', **kwargs):
super().__init__(**kwargs)
self.choices = choices
}}}
