Ionic header and footer
Ionic has many directives to help common layouts in mobile apps. Ionic headers and footers are important directives for showing proper context for any view in a mobile app. The exact directives, name and their usage are detailed as follows.
The <ion-header-bar> directive
This directive adds a fixed header bar above any content. You can also add a subheader by adding a CSS class bar-subheader on the second <ion-header-bar> directive, which will be shown below the primary header. The sample code for usage is as follows:
<ion-header-bar align-title="left" class="bar-positive">
<div class="buttons">
<button class="button" ng-click="back()">Back</button>
</div>
<h1 class="title">All about Books</h1>
<div class="buttons"> <button class="button">Logout</button>
</div>
</ion-header-bar>
There are two attributes available on the directive to add functionality to the header bar as shown in the following table:
