Component that represents each item in a list. The list item is composed of four parts that are represented with the left, center, right and expandable-content classes. These classes can be used to ensure that the content of the list items is properly aligned.
<ons-list-item>
<div class="left">Left</div>
<div class="center">Center</div>
<div class="right">Right</div>
<div class="expandable-content">Expandable content</div>
</ons-list-item>
There are also a number of classes (prefixed with list-item__*) that help when putting things like icons and thumbnails into the list items.
Creating lists in Onsen UI is very simple and they are one of the most important UI components in mobile apps.
Onsen UI provides three elements for creating lists:
<ons-list><ons-list-item><ons-list-header>The <ons-list> is used as the parent and for every item one <ons-list-item> element is used:
<ons-list>
<ons-list-item>Item A</ons-list-item>
<ons-list-item>Item B</ons-list-item>
<ons-list-item>Item C</ons-list-item>
</ons-list>
This will render as a list with three items.
To group items together you can use the <ons-list-header> element to create a header with text content.
<ons-list>
<ons-list-header>My friends</ons-list-header>
<ons-list-item>Alice</ons-list-item>
<ons-list-item>Bob</ons-list-item>
<ons-list-item>Eve</ons-list-item>
</ons-list>
You can use as many headers as you want in the same list.
In the previous examples the list items only contained simple text content. Onsen UI list items provide a secondary syntax where the list item is divided into four sections.
This can be used to add icons, thumbnails or even form elements to your list items:
<ons-list-item>
<div class="left">
<ons-icon icon="md-face" class="list-item__icon"></ons-icon>
</div>
<div class="center">
Icon and switch
</div>
<div class="right">
<ons-switch></ons-switch>
</div>
<div class="expandable-content">
Expandable content
</div>
</ons-list-item>
You can create list items that expand to reveal extra content when tapped by setting the expandable attribute.
The content that is shown when the list item is expanded is defined in div.expandable-content.
<ons-list-item expandable>
Tap to expand
<div class="expandable-content">This is shown when expanded</div>
</ons-list-item>
If div.right is not defined, a dropdown arrow is automatically added to the right side of the expandable list item.
The list item can also be expanded and contracted with the showExpansion and hideExpansion methods.
tappable attributeThe tappable attribute is used to give the user an indication when they tap a list item. In iOS the background color will change when tapped and on Android it will display the Material Design ripple effect.
<ons-list-item tappable>Tap me!</ons-list-item>
This is very useful in apps that perform some action or navigate to a new page when a list item is tapped.
There are a bunch of modifiers that can be used to customize the look of the lists and list items.
In Onsen UI modifiers are applied by adding the modifier attribute to an element. More than one can be added by separating them with spaces.
To create an inset list you can use the inset modifier on the <ons-list> element:
<ons-list modifier="inset">
...
</ons-list>
The longdivider and nodivider modifiers can be used to change the length or remove the divider (horizontal line) between list items completely. The default style for list items is a divider that doesn’t completely cover the whole screen. Instead it has some padding on the left to make it look more similar to native lists.
By adding the nodivider modifier the divider can be removed:
<ons-list>
<ons-list-item modifier="nodivider">Item A</ons-list-item>
<ons-list-item modifier="nodivider">Item B</ons-list-item>
</ons-list>
