Unfold introduces its own unfold.decorators.display decorator. By default, it has exactly the same behavior as the native django.contrib.admin.decorators.display but it adds customizations which help to extend the default logic.
@display(label=True), @display(label={"value1": "success"}) displays a result as a label. This option fits for different types of statuses. The label can be either a boolean indicating we want to use a label with the default color, or a dict where the dict is responsible for displaying labels in different colors. At the moment these color combinations are supported: success (green), info (blue), danger (red) and warning (orange).
@display(header=True) displays two pieces of information in one table cell in the results list. A good example is when we want to display customer information - the first line will be the customer's name and right below the name, the corresponding email address is displayed. A method with such a decorator is supposed to return a list with two elements return "Full name", "E-mail address". There is a third optional argument, which is the type of string and its value is displayed in a circle before the first two values on the front end. Its optimal usage is for displaying initials.

For the changelist, it is possible to apply dropdown=True which will display a clickable link. After clicking on the link, a dropdown will appear. There are two supported options for rendering the content of the dropdown:
items. This will render a classic list of items, which is a good option for displaying a list of related objects.content attribute which will display your custom content in the dropdown. This is handy for rendering complex layouts in the dropdown.The following example demonstrates how to create a dropdown with a list of items. The dropdown configuration accepts these options:
title (required) - The text displayed in the column that users click to open the dropdownitems (required) - List of items to display in the dropdown menu. Each item should have:title - Text to display for the itemlink (optional) - URL the item links tostriped (optional) - Boolean to enable alternating background colors for itemsheight (optional) - Maximum height in pixels before scrolling is enabledwidth (optional) - Width of the dropdown in pixelsThe dropdown will be positioned below the clicked element and will close when clicking outside or selecting an item.
class UserAdmin(ModelAdmin):
list_display = [
"display_dropdown",
]
@display(description=_("Status"), dropdown=True)
def display_dropdown(self, obj):
return {
# Clickable title displayed in the column
"title": "Custom dropdown title",
# Striped design for the items
"striped": True, # Optional
# Dropdown height. Will display scrollbar for longer content
"height": 200, # Optional
# Dropdown width
"width": 240, # Optional
"items": [
{
"title": "First title",
"link": "#" # Optional
},
{
"title": "Second title",
"link": "#" # Optional
},
]
}
You can also render a custom template inside a dropdown. Just pass the content parameter with template content. If you want to render more complex content, use render_to_string.
The dropdown configuration accepts these options when using custom template content:
title (required) - The text displayed in the column that users click to open the dropdowncontent (required) - HTML content or template string to display in the dropdownThe dropdown will be positioned below the clicked element and will close when clicking outside. The content can include any valid HTML or Django template syntax.
class UserAdmin(ModelAdmin):
list_display = [
"display_dropdown",
]
@display(description=_("Status"), dropdown=True)
def display_dropdown(self, obj):
return {
"title": "Custom dropdown title",
"content": "template content",
}
