    <p>I just wrote a class to do that:</p> <pre><code>from django.forms.widgets import Select from django.utils.encoding import force_unicode from itertools import chain from django.utils.html import escape, conditional_escape class ExtendedSelect(Select): """ A subclass of Select that adds the possibility to define additional properties on options. It works as Select, except that the ``choices`` parameter takes a list of 3 elements tuples containing ``(value, label, attrs)``, where ``attrs`` is a dict containing the additional attributes of the option. """ def render_options(self, choices, selected_choices): def render_option(option_value, option_label, attrs): option_value = force_unicode(option_value) selected_html = (option_value in selected_choices) and u' selected="selected"' or '' attrs_html = [] for k, v in attrs.items(): attrs_html.append('%s="%s"' % (k, escape(v))) if attrs_html: attrs_html = " " + " ".join(attrs_html) else: attrs_html = "" return u'&lt;option value="%s"%s%s&gt;%s&lt;/option&gt;' % ( escape(option_value), selected_html, attrs_html, conditional_escape(force_unicode(option_label))) # Normalize to strings. selected_choices = set([force_unicode(v) for v in selected_choices]) output = [] for option_value, option_label, option_attrs in chain(self.choices, choices): if isinstance(option_label, (list, tuple)): output.append(u'&lt;optgroup label="%s"&gt;' % escape(force_unicode(option_value))) for option in option_label: output.append(render_option(*option)) output.append(u'&lt;/optgroup&gt;') else: output.append(render_option(option_value, option_label, option_attrs)) return u'\n'.join(output) </code></pre> <p>Example:</p> <pre><code>select = ExtendedSelect(choices=( (1, "option 1", {"label": "label 1"}), (2, "option 2", {"label": "label 2"}), )) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
