I have a problem when I use ion-checkbox and ion-toggle components.
It seems, as per documentation, checked is false by default, but when use one of these by default is checked.



Is rendered active(checked = true)

If I put checked=“false” nothing happens.

Anyone have a clue about this?


Try this way may help you.

<ion-toggle [(ngModel)]="" formControlName="contact" id="contact" checked="false">Contactable</ion-toggle>

In ts file, = false;

Hello @Priyanka34,
Yess, it works for me, but I still think it’s a bug.

Well then remove the node module folder and add it again using this cmd: npm i and if not work after this then post your issue here with your project details.

@gokujy Ok, many thanks!

Tested. Deleted the node_modules and I ran npm i.

All ok.


There are too many proverbial cooks in the accepted kitchen. Choose only one of ngModel, a form control binding, and the checked attribute. Putting more than one on the same element is asking for phase-of-the-moon problems with expressions changing after they’ve been checked.
