Improve this doc

A sliding item is a list item that can be swiped to reveal buttons. It requires an Item component as a child and a List component as a parent. All buttons to reveal can be placed in the <ion-item-options> element.

Usage

<ion-list>
  <ion-item-sliding #item>
    <ion-item>
      Item
    </ion-item>
    <ion-item-options side="left">
      <button ion-button (click)="favorite(item)">Favorite</button>
      <button ion-button color="danger" (click)="share(item)">Share</button>
    </ion-item-options>

    <ion-item-options side="right">
      <button ion-button (click)="unread(item)">Unread</button>
    </ion-item-options>
  </ion-item-sliding>
</ion-list>

Swipe Direction

By default, the buttons are revealed when the sliding item is swiped from right to left, so the buttons are placed in the right side. But it's also possible to reveal them in the right side (sliding from left to right) by setting the side attribute on the ion-item-options element. Up to 2 ion-item-options can used at the same time in order to reveal two different sets of buttons depending the swipping direction.

<ion-item-options side="right">
  <button ion-button (click)="archive(item)">
    <ion-icon name="archive"></ion-icon>
    Archive
  </button>
</ion-item-options>

<ion-item-options side="left">
  <button ion-button (click)="archive(item)">
    <ion-icon name="archive"></ion-icon>
    Archive
  </button>
</ion-item-options>

Listening for events (ionDrag) and (ionSwipe)

It's possible to know the current relative position of the sliding item by subscribing to the (ionDrag)` event.

<ion-item-sliding (ionDrag)="logDrag($event)">
  <ion-item>Item</ion-item>
  <ion-item-options>
    <button ion-button>Favorite</button>
  </ion-item-options>
</ion-item-sliding>

Button Layout

If an icon is placed with text in the option button, by default it will display the icon on top of the text. This can be changed to display the icon to the left of the text by setting icon-left as an attribute on the <ion-item-options> element.

<ion-item-options icon-left>
  <button ion-button (click)="archive(item)">
    <ion-icon name="archive"></ion-icon>
    Archive
  </button>
</ion-item-options>

Instance Members

close()

Close the sliding item. Items can also be closed from the List.

The sliding item can be closed by grabbing a reference to ItemSliding. In the below example, the template reference variable slidingItem is placed on the element and passed to the share method.

<ion-list>
  <ion-item-sliding #slidingItem>
    <ion-item>
      Item
    </ion-item>
    <ion-item-options>
      <button ion-button (click)="share(slidingItem)">Share</button>
    </ion-item-options>
  </ion-item-sliding>
</ion-list>

import { Component } from '@angular/core';
import { ItemSliding } from 'ionic-angular';

@Component({...})
export class MyClass {
  constructor() { }

  share(slidingItem: ItemSliding) {
    slidingItem.close();
  }
}

Output Events

ondrag(item) {
  let percent = item.getSlidingPercent();
  if (percent > 0) {
    // positive
    console.log('right side');
  } else {
    // negative
    console.log('left side');
  }
  if (Math.abs(percent) > 1) {
    console.log('overscroll');
  }
}
