List

See also

Material Design spec, Lists

Lists are continuous, vertical indexes of text or images.

The class MDList in combination with a BaseListItem like OneLineListItem will create a list that expands as items are added to it, working nicely with Kivy’s ScrollView.

Due to the variety in sizes and controls in the Material Design spec, this module suffers from a certain level of complexity to keep the widgets compliant, flexible and performant.

For this KivyMD provides list items that try to cover the most common usecases, when those are insufficient, there’s a base class called BaseListItem which you can use to create your own list items. This documentation will only cover the provided ones, for custom implementations please refer to this module’s source code.

KivyMD provides the following list items classes for use:

Text only ListItems

• OneLineListItem

• TwoLineListItem

• ThreeLineListItem

ListItems with widget containers

These widgets will take other widgets that inherit from ILeftBody, ILeftBodyTouch, IRightBody or IRightBodyTouch and put them in their corresponding container.

As the name implies, ILeftBody and IRightBody will signal that the widget goes into the left or right container, respectively.

ILeftBodyTouch and IRightBodyTouch do the same thing, except these widgets will also receive touch events that occur within their surfaces.

KivyMD provides base classes such as ImageLeftWidget, ImageRightWidget, IconRightWidget, IconLeftWidget, based on the above classes.

Allows the use of items with custom widgets on the left.

• OneLineAvatarListItem

• TwoLineAvatarListItem

• ThreeLineAvatarListItem

• OneLineIconListItem

• TwoLineIconListItem

• ThreeLineIconListItem

It allows the use of elements with custom widgets on the left and the right.

• OneLineAvatarIconListItem

• TwoLineAvatarIconListItem

• ThreeLineAvatarIconListItem

API - kivymd.uix.list

class kivymd.uix.list.MDList(**kwargs)

ListItem container. Best used in conjunction with a kivy.uix.ScrollView.
