Wrong
|
|
-----
|
|
|
|
.. code-block:: python
|
|
|
|
menu = MDDropdownMenu(caller=self.screen.ids.button, items=menu_items)
|
|
menu.open()
|
|

Customization of menu item
|
|
--------------------------
|
|
|
|
.. image:: https://github.com/HeaTTheatR/KivyMD-data/raw/master/gallery/kivymddoc/menu-right.gif
|
|
:align: center
|
|
|
|
You must create a new class that inherits from the :class:`~RightContent` class:
|
|
|
|
.. code-block:: python
|
|
|
|
class RightContentCls(RightContent):
|
|
pass
|
|
|
|
Now in the KV rule you can create your own elements that will be displayed in
|
|
the menu item on the right:
|
|
|
|
.. code-block:: kv
|
|
|
|
<RightContentCls>
|
|
disabled: True
|
|
|
|
MDIconButton:
|
|
icon: root.icon
|
|
user_font_size: "16sp"
|
|
pos_hint: {"center_y": .5}
|
|
|
|
MDLabel:
|
|
text: root.text
|
|
font_style: "Caption"
|
|
size_hint_x: None
|
|
width: self.texture_size[0]
|
|
text_size: None, None
|
|
|
|
.. image:: https://github.com/HeaTTheatR/KivyMD-data/raw/master/gallery/kivymddoc/menu-right-detail.png
|
|
:align: center
|
|
|
|
Now create menu items as usual, but add the key ``right_content_cls`` whose
|
|
value is the class ``RightContentCls`` that you created:
|
|
|
|
.. code-block:: python
|
|
|
|
menu_items = [
|
|
{
|
|
"right_content_cls": RightContentCls(
|
|
text=f"R+{i}", icon="apple-keyboard-command",
|
|
),
|
|
"icon": "git",
|
|
"text": f"Item {i}",
|
|
}
|
|
for i in range(5)
|
|
]
|
|
self.menu = MDDropdownMenu(
|
|
caller=self.screen.ids.button, items=menu_items, width_mult=4
|
|
)
|
|
|

Menu without icons on the left
