I want to have a fixed logo in the Ionic2 framework. I have transitions between pages and the header and pages gets slid in. I want to know if I can keep the header / logo a constant above anything on the page.
<ion-header>
<a (click)="goToRoot()" ><img src="assets/img/topBar-iPad.png" alt=""/></a>
</ion-header>
<ion-content padding>
</ion-content>
I have tried it with the toolbar this doesn't work either.
If you want put an image in header, you can use this code:
<ion-header>
<ion-navbar>
<ion-title>Title</ion-title>
<ion-buttons end>
<img height="35px" width="35px" src="assets/img/topBar-iPad.png">
</ion-buttons>
</ion-navbar>
</ion-header>
This might get a bit tricky if you app becomes a bit more complex over time, however what you can do is add your <ion-header> element to your app.html file found in src -> app.
That sets it at top level above the pages you are navigation to.
If your app does become complex over time where only in some cases you want the toolbar to be fixed at the top you might need to either create a custom component based on the element or pass in a *ngIf ( or [hidden]="") and then write logic to support its visibility.

I would like to have a unique ion-title for each page of my ionic app (News, Search etc) but include a settings icon in the toolbar as well that will bring up a modal with a couple different options for the user to interact with. I want to avoid rebuilding the settings icon to keep my code DRY, prevent the unnecessary imports, and preserve separation of concerns.
news.page.html
<ion-header>
<ion-toolbar>
<ion-title>
News
</ion-title>
</ion-toolbar>
</ion-header>
app.component.html
<ion-app>
<ion-header>
<ion-icon (click)='openSettings()' slot='end' name='settings'></ion-icon>
</ion-header>
<ion-router-outlet></ion-router-outlet>
</ion-app>
As expected the page header overwrites the entire app header. I am thinking about building a separate settings icon component, but (I believe) that will require me to import it into every page.
Any help is appreciated.
I have a mobile app/website (in Ionic 3.25) under construction and wanted to support the desktop web browser experience without wasting all that screen space. I stumbled across Ion-Split-Pane. It seemed perfect from the documentation, allowing me to pop open the sidemenu as a full menu when a large screen was used. I set the code as recommended in the app.html file:
<ion-split-pane when="md">
<ion-menu [content]="content">
<ion-header>
<ion-toolbar>
<ion-title>Menu</ion-title>
</ion-toolbar>
</ion-header>
<ion-content>
<ion-list>
<button menuClose ion-item *ngFor="let p of pages" (click)="openPage(p)">
{{p.title}}
</button>
</ion-list>
</ion-content>
</ion-menu>
<!-- Disable swipe-to-go-back because it's poor UX to combine STGB with side menus -->
<ion-nav [root]="rootPage" #content swipeBackEnabled="false"></ion-nav>
</ion-split-pane>
The behavior I'm getting when using Ionic Serve is baffling. When I use a large screen (above somewhere around 922 pixels wide), I get a three pane experience, with a bunch of whitespace containing nothing in the far right. This was surprising, since I thought the app would use the available space:
When I then shrink below that size, the entire website/app disappears. The elements are still in the html, but nothing is drawn to the screen.
This behavior is so far from the documentation that I must have something wrong, but I'm not certain what. Anyone know how I could get this panel working?
After working on this for a while, I discovered my problem. It isn't mentioned explicitly in the documentation, so I'll post the answer here in case anyone else runs into it.
When converting a side-menu project to use Ion-Split-Pane, the content section needs to have the main keyword added to the <ion-nav> object. #content and [root] are not enough.
The amended code:
<ion-split-pane when="md">
<ion-menu [content]="content">
<ion-header>
<ion-toolbar>
<ion-title>Menu</ion-title>
</ion-toolbar>
</ion-header>
<ion-content>
<ion-list>
<button menuClose ion-item *ngFor="let p of pages" (click)="openPage(p)">
{{p.title}}
</button>
</ion-list>
</ion-content>
</ion-menu>
<!-- Disable swipe-to-go-back because it's poor UX to combine STGB with side menus -->
<ion-nav [root]="rootPage" main #content swipeBackEnabled="false"></ion-nav>
</ion-split-pane>
Without that line, the entire application is thrown into the 'menu' pane and simply disappears when going to the mobile view.
I'm trying to give my app a full-sized background. But I don't really know where to put it because wherever I put the image the navbar hasn't the background.
So I tried to surround my ion-content and my ion-footer with a <div> and hoped to give it the background-class. but in this case nothing I can't see anything on the screen. Right now my background is only inside the ion-content and the footer is still empty. How can I change it?
My code:
<ion-content class="bg-image" padding>
</ion-content>
<ion-footer>
<ion-toolbar>
</ion-toolbar>
</ion-footer>
Just like you can see in the docs, you need to add the fullscreen property to the ion-content:
<ion-content fullscreen="true">
<!-- ... -->
</ion-content>
If true, the content will scroll behind the headers and footers. This
effect can easily be seen by setting the toolbar to transparent.
I have a very simple app so far, but I can't figure out how to fix the overlapping of the content (header on top of the content). I have created a component header that contains the header as the name suggest.
header.html
<ion-header>
<ion-navbar color="dark">
<ion-title>
Some Title
</ion-title>
</ion-navbar>
</ion-header>
I have been trying to use it on different pages, but it always overlaps the content of the page.
page.html
<app-header></app-header>
<ion-content padding>
<h1>Some Page</h1>
</ion-content>
I have tried using div tag instead of ion-content, and also tried using class="has-header", but nothing seems to be working. Although, if don't use the header as a component such as the following, it works fine. But I want to use the header as a component so that I can reuse it on other pages.
page.html (don't want to have it like this)
<ion-header>
<ion-navbar color="dark">
<ion-title>
Some Title
</ion-title>
</ion-navbar>
</ion-header>
<ion-content padding>
<h1>Some Page</h1>
</ion-content>
As pointed out in this thread of Ionic official forum by #brandyshea of Ionic team, the thing is that in one page you can only have 3 kind of tags as top tags, everything else must go inside one of them. The 3 tags are:
<ion-header></ion-header>
<ion-content></ion-content>
<ion-footer></ion-footer>
I was trying to organize my app as #Hafiz and stumbled on the same problem, the solution has been to put my custom header (<ew-navigazione-top>) inside <ion-header> in each page.
<ion-header>
<ew-navigazione-top [ew_title]="navParams.get('label')" [ew_subtitle]="The subtitle"></ew-navigazione-top>
</ion-header>
P.S. This is the solution for Ionic 3. For previous versions on the same linked thread you can find other specific solutions.
try with below :
<app-header></app-header>
<ion-content style="margin-top:__px">
<h1>Some Page</h1>
</ion-content>
In my app I have at every page the "hideBackButton" on true. This works except on one page where that button appears next to the menu button (see screenshot). This back button hasn't any functionality here.
Is there a way to hide it? Perhaps by a css hack? Any help would be great.
There are pages where the back button should be visible, so I can't hide it in the entire app.
One way to hide the back button would be to set that page as the root page, instead of just pushing it. So instead of
this.navCtrl.push(ThePage)
try with
this.navCtrl.setRoot(ThePage)
That's one way to do it. If you don't want to change that, you can replace the ion-navbar for an ion-toolbar. So instead of
<ion-header>
<ion-navbar>
<ion-title>
Events Feed
</ion-title>
</ion-navbar>
</ion-header>
You can hide the back button with this:
<ion-header>
<ion-toolbar>
<ion-title>
Events Feed
</ion-title>
</ion-toolbar>
</ion-header>
I'd prefer the first fix, but I'm not sure of what are the requirements on your end.
