Component to define a list, and the container for ons-list-item(s).
Creating lists in Onsen UI is very simple and they are one of the most important UI components in mobile apps.
Onsen UI provides some elements for creating lists:
<ons-list><ons-list-item><ons-list-header><ons-list-title>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. The whole list can be preceded by a <ons-list-title> element.
<ons-list-title>People I know</ons-list-title>
<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-header>My enemies</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>
The child elements can also be label or even ons-if.
Apart from this, some extra classes are provided to style different parts of the list items:
list-item__title: Title inside the central part. Modifies font and position.list-item__subtitle: Subtitle inside the central part. Modifies font and position.list-item__icon: List item icon. Modifies size and alignment.list-item__thumbnail: List item thumbnail. Modifies size, borders and alignment.<ons-list-item>
<div class="left">
<img class="list-item__thumbnail" src="https://placekitten.com/g/40/40">
</div>
<div class="center">
<span class="list-item__title">Cutest kitty</span>
<span class="list-item__subtitle">On the Internet</span>
</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.
In order to prevent tappable effect when tapping on specific child elements like custom buttons, prevent-tap attribute can be added to any of the children. ons-* elements like ons-button or ons-checkbox are ignored by default.
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.
For example, 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>
ons-list-item adds extra classes to avoid CSS collisions. The final results is as follows:
<ons-list-item class="list-item">
<div class="top list-item__top">
<div class="left list-item__left">Left content</div>
<div class="center list-item__center">Center content</div>
<div class="right list-item__right">Right content</div>
</div>
<div class="expandable-content list-item__expandable-content">Expandable content</div>
</ons-list-item>
If none of those sections is provided, ons-list-item will wrap all its content inside div.list-item__center.
Attributes are added directly to the element. You can do this in HTML or JS.
HTML: <ons-list someAttribute="true" anotherAttribute><ons-list>
JS: document.querySelector('ons-list').setAttribute('someAttribute', 'true')
| Name | Type | Description |
|---|---|---|
| modifier | String | The appearance of the list. Optional. |
Modifiers are set in the modifier attribute. To use more than one, separate them by spaces. For example:
<ons-list modifier="inset
noborder"><ons-list>.
| Name | Description |
|---|---|
| inset | Inset list that doesn’t cover the whole width of the parent. |
| noborder | A list with no borders at the top and bottom. |
