Hide a tab on condition

I am trying to hide one of my tabs based on a condition, as follows:

    <ion-tab [root]="tab1" tabTitle="Tab1"></ion-tab>
    <ion-tab *ngIf="showTab2" [root]="tab2" tabTitle="Tab2"></ion-tab>
    <ion-tab [root]="tab3" tabTitle="Tab3"></ion-tab>

If tab 2 is not shown, based on the condition, it is still visible, but selecting tab2 shows tab3’s content. Selecting tab3 shows a black screen above the tabs.

Is there a way to get this to work, or is this a bug in ionic?

I believe tabs operate largely on numeric indexes under the hood, which is probably what’s causing what you’re seeing. From a UX perspective, having tabs move around physically strikes me as problematic anyway, so I would go with disabling it instead of trying to nuke it out of the DOM anyway.

Thanks @rapropos. From a UX perspective, my app has 2 modes. When the user switches to the second mode, one of the tabs is no longer relevant and therefore I hide it. As a workaround, I just created a second tabs page, and switch between them when the mode changes.

Don’t know for sure if this would work - but have you tried putting the condition on the ion-tabs component?

<ion-tabs *ngIf="showTab2">
    <ion-tab [root]="tab1" tabTitle="Tab1"></ion-tab>
    <ion-tab [root]="tab2" tabTitle="Tab2"></ion-tab>
    <ion-tab [root]="tab3" tabTitle="Tab3"></ion-tab>
<ion-tabs *ngIf="!showTab2">
    <ion-tab [root]="tab1" tabTitle="Tab1"></ion-tab>
    <ion-tab [root]="tab3" tabTitle="Tab3"></ion-tab>

That doesn’t seem to work.

But adding [enabled]=“isEnabled”, to the ion-tab seems to work. Where isEnabled is a boolean property on my tabs class.

Would you elaborate on how you got this to work?

Here’s what I did for dynamic tabs:

    <div  *ngFor="let tab of tabs" >
    <ion-tab [root]="tab.root" [tabTitle]="tab.title" 

on the backend I have

  tabs: Array<Object> = [ { title: "Home", root: HomePage, icon: "home" } ];
  allowedTabs: any;
  homepage: any = HomePage;
  newspage: any = "NewsPage"

    styleCtrl.getAppStyle().then( data => {
      let tabs = data.tabs;
      console.log( data.tabs );
      if( tabs.indexOf("EditHomepagePage") > -1 ) {
        this.tabs.push({ title: "Edit Pages", root: this.auth.getUserInfo ? LoginPage : "EditHomepagePage", icon: "brush" });
      if( tabs.indexOf("NewsPage") > -1 ) {
        this.tabs.push({ title: "News", root: "NewsPage", icon: "paper" });
      if( tabs.indexOf("DonatePage") > -1 ) {
        this.tabs.push({ title: "Donate", root: "DonatePage", icon: "card" });
      if( tabs.indexOf("CalendarPage") > -1 ) {
        this.tabs.push({ title: "Events", root: "CalendarPage", icon: "calendar" });
      if( tabs.indexOf("AboutPage") > -1 ) {
        this.tabs.push({ title: "About", root: "AboutPage", icon: "information-circle" });

I’m pulling async data from a database and then just pushing onto the tabs array. It works.

Thanks for sharing this solution.


  1. When you say “backend”, you’re talking about the component?
  2. How does the “allowedTabs” variable fit in?
  3. Is styleCtrl.getAppStyle() a user-defined function?

Try binding to [hidden] instead of *ngIf, that’ll keep it in DOM

For future reference, there’s actually the [show] attribute which works and is simple. I was struggling to find the solution only to see that I had already used the show attribute on another tab :smiley:


This totally fixed the problem…thanks a lot!

That works perfectly fine. Thank you very much for sharing
