I'm trying to align a combo and an input text with ionic2.
When i use ion-item inside a ion-grid, it always occupies 50% of the page, without respecting the configured size.
Any idea how to do this?
<ion-row>
<ion-col width-30>
<ion-item>
<ion-select [(ngModel)]="type">
<ion-option value="work">work</ion-option>
<ion-option value="home">home</ion-option>
<ion-option value="cel">cel</ion-option>
</ion-select>
</ion-item>
</ion-col>
<ion-col width-70>
<ion-item>
<ion-input type="text" [(ngModel)]="phone" clearInput placeholder="Phone"></ion-input>
</ion-item>
</ion-col>
</ion-row>

Just like you can see in Ionic2 docs these are the values you can use to set the width of the columns:
Explicit Column Percentage Attributes
width-10 10%
width-20 20%
width-25 25%
width-33 33.3333%
width-50 50%
width-67 66.6666%
width-75 75%
width-80 80%
width-90 90%
That's why if you try to use width-30 or width-70, nothing will change. Instead, you can align those two fields by using width-33 and width-67 like you can see in this working plunker.
There, if you inspect the ion-col element in the browser, you'll see this style rule being applied:
ion-col[width-33], ion-col[width-34] {
-webkit-box-flex: 0;
-webkit-flex: 0 0 33.3333%;
-ms-flex: 0 0 33.3333%;
flex: 0 0 33.3333%;
max-width: 33.3333%;
}
And
ion-col[width-66], ion-col[width-67] {
-webkit-box-flex: 0;
-webkit-flex: 0 0 66.6666%;
-ms-flex: 0 0 66.6666%;
flex: 0 0 66.6666%;
max-width: 66.6666%;
}
Which was not happening with width-30 and width-70.
Try giving ion-item as the parent tag for ion-row
<ion-item>
<ion-row>
<ion-col width-30>
<ion-select [(ngModel)]="type">
<ion-option value="work">work</ion-option>
<ion-option value="home">home</ion-option>
<ion-option value="cel">cel</ion-option>
</ion-select>
</ion-item>
</ion-col>
<ion-col width-70>
<ion-item>
<ion-input type="text" [(ngModel)]="phone" clearInput placeholder="Phone"></ion-input>
</ion-col>
</ion-row>
</ion-item>

Hi I have a select box in ionic 2 as.
//home.html
<ion-item>
<ion-label>Select City</ion-label>
<ion-select [(ngModel)]="city" (ionChange) ="getDoors()">
<ion-option *ngFor="let city of cities" [value]="city.id">
{{city.name}}</ion-option>
</ion-select>
</ion-item>
//home.ts
getDoors(){
console.log(this.cities);
}
But when I am changing option it throw an error, Error trying to diff '1'
can anyone let me know the issue here
Thanks advance
There are 2 methods through which you can get the value of the selected Item.
Method 1
//home.html
<ion-item>
<ion-label>Select City</ion-label>
<ion-select [(ngModel)]="city" (ionChange) ="getDoors($event)">
<ion-option *ngFor="let city of cities" [value]="city.id">
{{city.name}}</ion-option>
</ion-select>
</ion-item>
//home.ts
getDoors($event){
console.log($event);
}
Method 2
By using ngModel
//home.html
<ion-item>
<ion-label>Select City</ion-label>
<ion-select [(ngModel)]="selectedcity" (ionChange) ="getDoors($event)">
<ion-option *ngFor="let city of cities" [value]="city.id">
{{city.name}}</ion-option>
</ion-select>
</ion-item>
//home.ts
selectedcity: city
getSelectedCity(){
return this.selectedcity;
}
Perhaps it's because you named your ngModel city and your *ngFor uses city as well. Might cause a conflict. I would change your ngModel to
[(ngModel)]="selectedCity"
I am using ionic 2 and I would like to get a result like this:
For now, I have a simple ion-list :
<ion-list radio-group formControlName="type">
<ion-col col-4 >
<ion-item>
<ion-label>Breakfast</ion-label>
<ion-radio value="breakfast" ></ion-radio>
</ion-item>
</ion-col>
<ion-col col-4 >
<ion-item>
<ion-label>Diner</ion-label>
<ion-radio value="diner" checked="true">
</ion-radio>
</ion-item>
</ion-col>
<ion-col col-4 >
<ion-item>
<ion-label>Lunch</ion-label>
<ion-radio value="lunch" checked="true">
</ion-radio>
</ion-item> </ion-col>
my result :
thanks
You need to implement Ionic Segment to get the expected result.
have a look Ionic-Segment
I have a form in my Ionic 2 project that has 2 ion-select dropdowns. When the user selects an option in the 1st dropdown it generates the options of the 2nd dropdown. This works fine. My question is, if the user changes their selection for the 1st dropdown the selected 2nd option does not clear out. How do I get it to clear so the user is not confused about the options for the new select?
<ion-item>
<ion-label>
<img height="100" src="assets/img/customer.png" alt="Customer"/>
</ion-label>
<ion-select [(ngModel)]="customer" name="customer" (ionChange)="addBuildings(customer);" placeholder="Customer">
<ion-option *ngFor="let customer of customers" value="{{customer.name}}">{{customer.name}}</ion-option>
</ion-select>
</ion-item>
<ion-item>
<ion-label>
<img height="100" src="assets/img/building.png" alt="Building"/>
</ion-label>
<ion-select [(ngModel)]="building" name="building" placeholder="Building">
<ion-option *ngFor="let building of buildings" value="{{building.name}}">{{building.name}}</ion-option>
</ion-select>
</ion-item>
I solved this by using the ngModel and setting it to null in the .ts at the beginning of the .addBuildings() function.
I want to display label and input on left side sequentially and button/icon on right side.
i have tried with using grid as
<ion-grid>
<ion-row>
<ion-col width-10>
<ion-icon name="phone-portrait"></ion-icon>
</ion-col>
<ion-col width-70>
<ion-input type="text" placeholder="Mobile no"></ion-input>
</ion-col>
<ion-col width-10>
<ion-icon name="contacts" (click)="pickContactNo()"></ion-icon>
</ion-col>
</ion-row>
</ion-grid>
It display's it inline but the input box slightly goes below.
also tried with item-left and item-right properties. but cant able to do.
Try this:
<ion-item>
<ion-icon item-left name="phone-portrait"></ion-icon>
<ion-input type="text" placeholder="Mobile no"></ion-input>
<ion-icon item-right name="contacts" (click)="pickContactNo()"></ion-icon>
</ion-item>
You will probably have to override some of the css in the elements of ion-grid otherwise.
UPDATE From ionic#3.4.0 :
Thanks to #keldar for the comment. According to the docs,directional properties item-left and item--right are deprecated and you would need to use item-start and item-end which would allow to support both Right to Left and Left to Right.
<ion-item>
<ion-icon item-start name="phone-portrait"></ion-icon>
<ion-input type="text" placeholder="Mobile no"></ion-input>
<ion-icon item-end name="contacts" (click)="pickContactNo()"></ion-icon>
</ion-item>
ion-row has several attributes (see Row). The one that looks suitable for you is align-items-center.
So, you can try this:
<ion-grid>
<ion-row align-items-center>
...
if you add new col, it mean that will be another column and you don't have unspecified the dimensions of these
When you add
you can insert one ion-item to insert everything on the same line without static sizes.
<ion-item>
<ion-icon item-start name="phone-portrait"></ion-icon>
<ion-input type="text" placeholder="Mobile no"></ion-input>
<ion-icon item-end name="contacts" (click)="pickContactNo()"></ion-icon>
</ion-item>
I am trying to make a custom item containing 3 inputs in a list in ionic 2, but it's not working. When I put only 1 input, there's no problem. But if I put other tag with "
<ion-item *ngFor="let pergunta of avaliacao; let i=index">
<ion-row>
<ion-input placeholder="Pergunta" [(ngModel)]="pergunta.descricao" clearInput></ion-input>
</ion-row>
<ion-row>
<ion-textarea [(ngModel)]="pergunta.opcoes"></ion-textarea>
</ion-row>
<ion-row>
<ion-label>Obrigatória</ion-label><ion-checkbox [(ngModel)]="pergunta.obrigatoria"></ion-checkbox>
</ion-row>
</ion-item>
I did it. It seems I can't put several input inside ion-item. Just replaced ion-item for div
