name is the label of the menu item.
|
|
|
|
icon is the icon to be displayed for the menu item. Icon can be the
|
|
name of an SVG icon from the static/theme/icons directory. In this
|
|
case, the icon name starts with the string 'fa-' (a tribute to the
|
|
fork-awesome project). Alternatively, the icon can also be a file under
|
|
the directory freedombox/modules/<app>/static/icons/, provided without
|
|
an extension. SVG icons are preferred. Currently, both PNG and SVG
|
|
icons with the same name are used. For example, if the value of icon is
|
|
'myicon' and app_id in App class is 'myapp', then two icons files
|
|
freedombox/modules/myapp/static/icons/myicon.svg and
|
|
freedombox/modules/myapp/static/icons/myicon.png are used in the
|
|
interface.
|
|
|
|
tags is a list of tags that describe the app. Tags help users to find
|
|
similar apps or alternatives and discover use cases.
|
|
|
|
url_name is the name of url location that will be activated when the
|
|
menu item is selected. This is not optional. url_args and url_kwargs
|
|
are sent to reverse() when resolving url from url_name.
|
|
|
|
parent_url_name optionally specifies the menu item under which this
|
|
menu item should become a child.
|
|
|
|
order is the numerical rank of this item within the menu. Lower order
|
|
items appear closest to the top/left of the menu. By convention, we use
|
|
the spectrum between 0 and 100 to rank orders, but feel free to
|
|
disregard that. If you need more granularity, don't bother renumbering
|
|
things. Feel free to use fractional orders.
|
|
|
|
advanced decides whether to show the menu item only in advanced mode.
