I have a list of items in my app. This is the code
<ion-list>
<ion-item-sliding #item *ngFor="let productSize of productSizes">
<ion-item>
... some stuff
</ion-item>
<ion-item-options side="right">
<button ion-button color="danger" (click)="RemoveItem(productSize)">X</button>
</ion-item-options>
</ion-item-sliding>
</ion-list>
When the user slides left, there is a button delete that shows up and lets the user to delete the item.
I want to do this without the remove button. When he slides left and releases the mouse or touch, delete the item.
You can use the expandable option combined with the (ionSwipe) event.
So your options will look like this:
<ion-item-options side="right" (ionSwipe)="RemoveItem(productSize)">
and your button:
<button ion-button color="danger" expandable (click)="RemoveItem(productSize)">X</button>
Check out the docs here (under Expandable Options).

The reorder function seems to be attaching reorder icons to all the nested items within my ngFor list. So with 2 items being a checkbox and a text-input, I get 2 extra (3 total) reorder icons per list item. Only one of them works, the other two are just visual. I need to remove the other 2 and just have one clean reorder icon per item, or something to that effect.
I have tried removing the nested items, but the checkbox and text-input don't work.
/// Here is the HTML ///
<ion-list no-lines [reorder]="reorderIsEnabled" (ionItemReorder)="itemReordered($event)" id="lowtrimlist">
<ion-item-sliding *ngFor="let task of tasks; let taskIndex = index">
<ion-item>
<ion-row>
<ion-col col-1>
<ion-item no-lines>
<ion-checkbox></ion-checkbox>
</ion-item>
</ion-col>
<ion-col col-11>
<ion-item>
<ion-textarea>
</ion-textarea>
</ion-item>
</ion-col>
</ion-row>
</ion-item>
<ion-item-options side="right">
<button ion-button color="danger"(click)="delete()">
<ion-icon name="trash"></ion-icon>
</button>
</ion-item-options>
</ion-item-sliding>
</ion-list>
What I'm looking for is there to be one single reorder icon per line item, but instead there are 3. It seems like the reorder function picks up and tries to label every internal item.
Follow an Ionic 4 tutorial
Based on your comments it's not clear where you have got your method from but it's not what the documentation says, and it's not what I have seen before.
I suspect you are using some kind of legacy support mode from earlier version of Ionic.
I actually just learned to use ion-reorder myself recently and I followed this tutorial:
https://www.freakyjolly.com/ionic-4-ion-reorder-list-drag-drop-sorting-list-in-ionic-4-using-ion-reorder-component/
Did you paste the right html snippet?
I would expect to see a combination of ion-reorder-group and ion-reorder like this:
<ion-list>
<ion-reorder-group (ionItemReorder)="onReorderItems($event)" [disabled]="!isGameRunning">
<ion-item *ngFor="let item of listItems" [class]="item?.cssClass">
<ion-label>{{ item?.name }} </ion-label>
<ion-reorder slot="end"></ion-reorder>
</ion-item>
</ion-reorder-group>
</ion-list>
Test
As a test I just put an extra ion-item inside the ion-item above and ran it in a little game I made recently:
<ion-list>
<ion-reorder-group (ionItemReorder)="onItemReorder($event)" [disabled]="!isGameRunning">
<ion-item *ngFor="let item of listItems" [class]="item?.cssClass">
<ion-label>{{ item?.name }} </ion-label>
<ion-item>inner item</ion-item>
<ion-reorder slot="end"></ion-reorder>
</ion-item>
</ion-reorder-group>
</ion-list>
It rendered ok:
Implementing programmatically?
All of this is leading me to think that its a coding error. Are you trying to implement the reordering programmatically?
Please share your snippet but you just need to use the ion-reorder-group, ion-reorder and disable="false" to display it.
When I click on the label of an ion-item the checkbox is triggered.
I want to find a way of preventing this from happening as I want to trigger another function when clicking the label.
I found this answer for Ionic 3: https://forum.ionicframework.com/t/solved-can-i-disable-a-checkbox-from-activating-when-clicking-on-a-label/95120
However, it is not working for Ionic 4.
<ion-item>
<ion-icon [name]="setIconDoc(item.document.documentType)" color="primary" (click)="editDocument(item.document)"></ion-icon>
<ion-label padding-start color="none" (click)="editDocument(item.document)"> {{ item.document.customer.name }}
</ion-label>
<ion-checkbox slot="end" color="success" [(ngModel)]="item.isChecked">
</ion-checkbox>
</ion-item>
I'd like to have two behaviors:
- When clicking in the Checkbox trigger just the checkbox.
- When clicking on the label or the icon open a modal to edit my document.
I just had a similar problem and found a nice solution for it in ionic 4 by using the slots of ion-item.
<ion-item lines="full">
<ion-icon slot="start" name="at" (click)="iconClicked()"></ion-icon>
<ion-label slot="start" (click)="labelClicked()">
This is a separately clickable label
</ion-label>
<ion-checkbox slot="end"></ion-checkbox>
</ion-item>
Explanation
The elements in the start slot of the ion-item are not triggered when clicking the checkbox.
The start slot has no bottom border by default so it must be set by adding lines="full" to the ion-item;
Be aware, that the main slot still is rendered with a large width. That may lead to some hidden content. In this case this can be fixed with a css tweak like this.
ion-item ion-label {
overflow: visible;
}
I found another solution. I added another hidden checkbox in the item.
<ion-item *ngFor="let task of tasks;let i of index;" padding margin>
<ion-checkbox slot="start" color="success" (click)="DeleteTask($event, task)"></ion-checkbox>
<!-- another checkbox otherwise item clicks triggers checkbox click -->
<ion-checkbox hidden=true ></ion-checkbox>
<ion-label >
{{task.Name}}
</ion-label>
<ion-reorder slot="end"></ion-reorder>
You can also wrap the checkbox in a slotted div, which appears to break the link between the item and the checkbox.
<ion-item (click)="itemHandler()">
<ion-icon />
<ion-label>Label</ion-label>
<ion-checkbox (click)="checkboxHandler()" />
</ion-item>
If you put the click handler on the ion-item then it will handle clicks from anywhere on the ion-item. However, that includes clicks from the checkbox, so you have to make sure to also call event.stopPropagation() in the checkbox click handler.
Hey guys I am currently working on a project with ionic and the menu has been giving more problems than it should.
Recently I have been trying to add the menu close attribute, but where ever I put it does not seem to matter. I have been placing it with a click action, with an ion-item prepend, and other failed attempts.
Below is a piece of my code for my app.component.html
<ion-menu contentId="potifyMenu" side="start">
<ion-header>
<ion-toolbar>
<ion-title>Additional Resources</ion-title>
</ion-toolbar>
</ion-header>
<ion-content>
<ion-list>
<ion-item>
<ion-button menuClose expand="full" (click)="map_go()">
<ion-icon name="checkmark-circle-outline"></ion-icon> Completed Work Orders
</ion-button>
</ion-item>
<ion-item>
<ion-button expand="block" fill="outline" menuClose ion-item (click)="complete_go()">
<ion-icon name="checkmark-circle-outline"></ion-icon> Completed Work Orders
</ion-button>
</ion-item>
<ion-item>
<ion-button expand="full" ion-button menuClose (click)="complete_go()">
<ion-icon name="checkmark-circle-outline"></ion-icon> Cmpleted Work Orders
</ion-button>
</ion-item>
<ion-item>
<ion-button expand="full" menuClose (click)="complete_go()">
<ion-icon slot="start" name="checkmark-circle-outline"></ion-icon> Completed Work Orders
</ion-button>
</ion-item>
</ion-list>
</ion-content>
</ion-menu>
Figured out a solution from a past post that never showed up in my million of searches.
just needed to encapusulate the button with a toggle
"<ion-menu-toggle>
<ion-button>Toggle Menu</ion-button>
</ion-menu-toggle>

How to toggle Menu in Ionic 4
I have the same issue as menuClose directive work perfectly in ionic 3 to control toggle. In ionic 5 use ion-menu-toggle component to toggle menu close and open on the menu item. If you don't want to add toggle menu for menu item having submenu then don't use ion-menu-toggle component on those menu items.
Ionic 5 control menu and submenu close and dropdown
I'm Trying to hide/show elements of a ion-list depending of a boolean variable which is changed when a button is clicked.
The problem is that if I try with *ngIf="{{editMode}}" the ionic serve --lab shows blank screen on browser.
<ion-item-sliding *ngFor="let item of items" (click)="itemTapped($event, item)">
<ion-item>
<ion-icon item-left name="rose" *ngIf="{{editMode}}"></ion-icon>
<ion-icon name="{{item.icon}}" item-left></ion-icon>
{{item.title}}
<div class="item-note" item-right>
{{item.note}}
</div>
</ion-item>
And if i try with *ngIf="'editMode'" the result of click on button is nothing.
When I click on a nav bar button the boolen variable is modified to true/false.
What would be wrong?
Check here
You have to do *ngIf="editMode"
*ngIf="'editMode'" - Here you are just taking the string editMode which is truthy and button will not work.
Is there a simple way to make ion-cards swipe rather than stack vertically one above the other?
I currently have the cards stacking vertically using this code:
<ion-content class="outer-content speaker-list">
<ion-card *ngFor="#speaker of speakers" class="speaker">
<ion-card-header>
<ion-item>
<ion-avatar item-left>
<img [src]="speaker.profilePic">
</ion-avatar>
{{speaker.name}}
</ion-item>
</ion-card-header>
<ion-card-content class="outer-content">
<ion-list>
<button ion-item *ngFor="#session of speaker.sessions" (click)="goToSessionDetail(session)">
<h3>{{session.name}}</h3>
</button>
<button ion-item (click)="goToSpeakerDetail(speaker)">
<h3>About {{speaker.name}}</h3>
</button>
</ion-list>
</ion-card-content>
<ion-item>
<button (click)="goToSpeakerTwitter(speaker)" clear item-left>
<ion-icon name="logo-twitter"></ion-icon>
Tweet
</button>
<button (click)="openSpeakerShare(speaker)" clear item-right>
<ion-icon name="share"></ion-icon>
Share
</button>
</ion-item>
</ion-card>
</ion-content>
I am looking for a simple way to get them to swipe rather than stack. There are various plugins that do Tinder like swiping cards but I was wondering if there is a setting that can be given to ion-card to make the cards do a simple swipe (I am not looking for the Tinder visual effect) like a carousel.
I am using ionic V2.
