ion-affix

Allows for creating affixed (sticky) ion-list-header, ion-item-divider and ion-card for newest Ionic framework.

Kudos to Collin Donahue-Oponski and his initial idea shown in this gist.

See it

Get it

from npm

npm install --save ion-affix

Use it

Import IonAffixModule in your app.module.ts

@NgModule({
    ...
    imports: [
        IonAffixModule
    ]
    ...
})
export class AppModule {
}

and add the directive ion-affix to any ion-list-header, ion-item-divider or ion-item (inside ion-card) that should be sticky. You also need to provide a reference to the parent ion-content.

<ion-content padding #content>
   <ion-list>
       <ion-list-header ion-affix [content]="content" (click)="test()">Group 1</ion-list-header>
       <ion-item *ngFor="let item of items">{{item}}</ion-item>
   </ion-list>
   <ion-list>
       <ion-list-header ion-affix [content]="content">Group 2</ion-list-header>
       <ion-item *ngFor="let item of items">{{item}}</ion-item>
   </ion-list>
</ion-content>

<ion-content padding #content>
   <ion-item-group>
       <ion-item-divider ion-affix [content]="content" (click)="test()">Group 1 (click me!)</ion-item-divider>
       <ion-item *ngFor="let item of items">{{item}}</ion-item>
   </ion-item-group>
   <ion-item-group>
       <ion-item-divider ion-affix [content]="content">Group 2</ion-item-divider>
       <ion-item *ngFor="let item of items">{{item}}</ion-item>
   </ion-item-group>
</ion-content>

<ion-content padding #content>
    <ion-card>
        <ion-item ion-affix [content]="content" no-lines>
            <ion-avatar item-start>
                <img src="assets/img/marty-avatar.png">
            </ion-avatar>
            <h2>Marty McFly</h2>
            <p>November 5, 1955</p>
        </ion-item>
        <img src="assets/img/advance-card-bttf.png">
        <ion-card-content>
            <p>Wait a minute. Wait a minute, Doc. Uhhh... Are you telling me that you built a time machine... out of a DeLorean?! Whoa. This is heavy.</p>
        </ion-card-content>
        <ion-row>
            <ion-col>
                <button ion-button color="primary" clear small icon-start>
                    <ion-icon name='thumbs-up'></ion-icon>

            </ion-col>
            <ion-col>
                <button ion-button color="primary" clear small icon-start>
                    <ion-icon name='text'></ion-icon>

                </button>
            </ion-col>
            <ion-col align-self-center text-center>

</ion-content>

Explain it

To be able use custom Angular directives on a sticky header I decided to make the original ion-list-header element sticky instead of its clone. This is the major difference to the gist shown above and I did it mainly because I have no idea how to do a $compile(clone) known from AngularJS with Angular 2.
