Generally it is placed in a list with other * items. It can easily be swiped, deleted, reordered, edited, and more. An item is only required to * be in a [List](../../list/List) if manipulating the item via gestures is required. It requires an * [ItemSliding](../ItemSliding) wrapper element in order to be swiped. * * * ## Common Usage * There are a few elements that are considered items, but not all of them are styled to look the same. * The basic item can be written as an `<ion-item>` element or it can be added to any element by adding * `ion-item` as an attribute. List headers and item dividers, although styled differently, are also items * and can be written as `<ion-list-header>` and `<ion-item-divider>`, respectively. * * ### As an Element * A basic item should be written as a `<ion-item>` element when it is not clickable. * * ```html * <ion-item> * Item * </ion-item> * ``` * * A list header should be written as `<ion-list-header>`. * * ```html * <ion-list-header> * List Header * </ion-list-header> * ``` * * An item divider should be written as `<ion-item-divider>`. * * ```html * <ion-item-divider> * Item Divider * </ion-item-divider> * ``` * * ### As an Attribute * The attribute `ion-item` should be added to a `<button>` when the item can be clicked or tapped. It * should be added to an `<a>` element when the item needs to contain a `href`. It can be added as an * attribute to any element to take on the item styling. * * ```html * <button ion-item (click)="buttonClick()"> * Button Item * </button> * * <a ion-item href="https://www.ionicframework.com"> * Anchor Item * </a> * ``` * * Note: do not add `ion-item` as an attribute to an `<ion-list-header>` or `<ion-item-divider>` element * as they are already items and their styling will be changed to look like a basic item. * * ## Detail Arrows * By default, `<button>` and `<a>` elements with the `ion-item` attribute will display a right arrow icon * on `ios` mode. To hide the right arrow icon on either of these elements, add the `detail-none` attribute * to the item. To show the right arrow icon on an element that doesn't display it naturally, add the * `detail-push` attribute to the item. * * ```html * <ion-item detail-push> * Item with Detail Arrow * </ion-item> * * <button ion-item (click)="buttonClick()"> * Button Item with Detail Arrow * </button> * * <a ion-item detail-none href="https://www.ionicframework.com"> * Anchor Item with no Detail Arrow * </a> * ``` * * This feature is not enabled by default for `md` and `wp` modes, but it can be enabled by setting the * Sass variables `$item-md-detail-push-show` and `$item-wp-detail-push-show`, respectively, to `true`. * It can also be disabled for ios by setting `$item-ios-detail-push-show` to `false`. See the * [theming documentation](http://ionicframework.com/docs/theming/overriding-ionic-variables/) for * more information on overriding Sass variables. * * * ## Item Placement * Items rely heavily on content projection to position content. The item grabs content based on the * element or attribute and positions it that way. This logic makes it possible to write a complex * item with simple, understandable markup without having to worry about styling and positioning * the elements. * * The below chart details the attributes item looks for and where it will place the element with * that attribute inside of the item: * * | Attribute | Description | * |----------------|----------------------------------------------------------------------------------------------------- | * | `item-start` | Placed to the left of all other elements, outside of the inner item. | * | `item-end` | Placed to the right of all other elements, inside of the inner item, outside of the input wrapper. | * | `item-content` | Placed to the right of any `ion-label`, inside of the input wrapper. | * * ### Checkboxes, Radios and Toggles * [Checkboxes](../../checkbox/Checkbox) are positioned in the same place as the `item-start` attribute. * [Radios](../../radio/RadioButton) and [Toggles](../../toggle/Toggle) are positioned in the same place * as the `item-end` attribute. All of these components can be positioned differently by adding the * `item-start` or `item-end` attribute. * * ### Content and Inputs * A [Label](../../label/Label) is placed inside of the item to the left of all content and inputs. The * following components are all placed in the same position as the `item-content` attribute: [Select](../../select/Select), * [Input](../../input/Input), [TextArea](../../input/TextArea), [DateTime](../../datetime/DateTime), and * [Range](../../range/Range). * * Any element directly placed inside of an `<ion-item>` that does not have one of the previously mentioned * attributes and isn't one of the above elements will be placed inside of a [Label](../../label/Label). * * ### Text Alignment * By default, Items will align text to the left and add an ellipsis when the text is wider than the item. * See the [Utility Attributes Documentation](../../../../theming/css-utilities/) for attributes that can * be added to `ion-item` to transform the text. * * @usage * * ```html * <ion-list> * * <ion-list-header> * Header * </ion-list-header> * * <ion-item> * Item * </ion-item> * * <ion-item detail-push> * Item with Detail Arrow * </ion-item> * * <button ion-item (click)="buttonClick()"> * Button Item * </button> * * <ion-item-divider> * Item Divider * </ion-item-divider> * * <button ion-item detail-none (click)="buttonClick()"> * Button Item with no Detail Arrow * </button> * * <a ion-item href="https://www.ionicframework.com"> * Anchor Item * </a> * * <ion-item no-lines> * Item with no border * </ion-item> * * <ion-item text-wrap> * Multiline text that should wrap when it is too long * to fit on one line in the item. * </ion-item> * * </ion-list> * ``` * * * @advanced * * ```html * <ion-list> * * <!-- List header with buttons on each side --> * <ion-list-header> * <button ion-button item-start (click)="buttonClick()">Button</button> * List Header * <button ion-button outline item-end (click)="buttonClick()">Outline</button> * </ion-list-header> * * <!-- Loops through and creates multiple items --> * <ion-item *ngFor="let item of items"> * Item {% raw %}{{item}}{% endraw %} * </ion-item> * * <!-- Button item with an icon on the left --> * <button ion-item> * <ion-icon name="star" item-start></ion-icon> * Button Item * </button> * * <!-- Item with a label and content --> * <ion-item> * <ion-label> * Item Label * </ion-label> * <div item-content> * Item Content next to the label * </div> * </ion-item> * * <!-- Item with left and right buttons --> * <ion-item> * <button ion-button item-start (click)="buttonClick()">Button</button> * Item * <button ion-button outline item-end (click)="buttonClick()">Outline</button> * </ion-item> * * <!-- Item divider with a right button --> * <ion-item-divider> * Item Divider * <button ion-button item-end>Button</button> * </ion-item-divider> * * <!-- Disabled button item with left and right buttons --> * <button ion-item disabled> * <button ion-button item-start (click)="buttonClick()"> * <ion-icon name="home"></ion-icon> * Left Icon * </button> * Disabled Button Item * <button ion-button outline item-end (click)="buttonClick()"> * <ion-icon name="star"></ion-icon> * Left Icon * </button> * </button> * * <!-- Item with an avatar on the left and button on the right --> * <ion-item> * <ion-avatar item-start> * <img src="img/my-avatar.png"> * </ion-avatar> * Avatar Item * <button ion-button outline item-end>View</button> * </ion-item> * * <!-- Item with a thumbnail on the right --> * <ion-item> * <h2>Item</h2> * <p>Item Paragraph</p> * <ion-thumbnail item-end> * <img src="img/my-thumbnail.png"> * </ion-thumbnail> * </ion-item> * * <!-- Sliding item --> * <ion-item-sliding> * <ion-item> * Item * </ion-item> * <ion-item-options> * <button ion-button color="primary" (click)="archive()">Archive</button> * </ion-item-options> * </ion-item-sliding> * * </ion-list> * ``` * * * @demo /docs/demos/src/item/ * @see {@link /docs/components#lists List Component Docs} * @see {@link ../../list/List List API Docs} * @see {@link ../ItemSliding ItemSliding API Docs} */ export declare class Item extends Ion { _ids: number; _inputs: Array<string>; _label: Label; _viewLabel: boolean; _name: string; _hasReorder: boolean; /** * @hidden */ id: string; /** * @hidden */ labelId: string; constructor(form: Form, config: Config, elementRef: ElementRef, renderer: Renderer, reorder: ItemReorder); /** * @hidden */ registerInput(type: string): string; /** * @hidden */ ngAfterContentInit(): void; /** * @hidden */ _updateColor(newColor: string, componentName?: string): void; /** * @hidden */ _setName(elementRef: ElementRef): void; /** * @hidden */ getLabelText(): string; /** * @hidden */ contentLabel: Label; /** * @hidden */ viewLabel: Label; /** * @hidden */ _buttons: QueryList<Button>; /** * @hidden */ _icons: QueryList<Icon>; }
