## Menu item position
|
||||
|
||||
You can make use of `position` and `id` to control how the item would be placed
|
||||
when building a menu with `Menu.buildFromTemplate`.
|
||||
|
||||
The `position` attribute of `MenuItem` has the form `[placement]=[id]` where
|
||||
placement is one of `before`, `after`, or `endof` and `id` is the unique ID of
|
||||
an existing item in the menu:
|
||||
|
||||
* `before` - Inserts this item before the id referenced item. If the
|
||||
referenced item doesn't exist the item will be inserted at the end of
|
||||
the menu.
|
||||
* `after` - Inserts this item after id referenced item. If the referenced
|
||||
item doesn't exist the item will be inserted at the end of the menu.
|
||||
* `endof` - Inserts this item at the end of the logical group containing
|
||||
the id referenced item. (Groups are created by separator items). If
|
||||
the referenced item doesn't exist a new separator group is created with
|
||||
the given id and this item is inserted after that separator.
|
||||
|
||||
When an item is positioned following unpositioned items are inserted after
|
||||
it, until a new item is positioned. So if you want to position a group of
|
||||
menu items in the same location you only need to specify a position for
|
||||
the first item.
