bug: ion-checkbox is toggled by ion-item click

[bsbechtel]

Bug Report

Ionic version:

[x] 4.x

Current behavior:

If you have the following markup, any click or tap on the ion-item will toggle the ion-checkbox:

    <ion-item>
      <ion-checkbox slot="start"></ion-checkbox>
      <div>Testing!</div>
    </ion-item>

Expected behavior:

The ion-checkbox should only toggle when it is clicked, or the click event from the ion-item should be cancellable.

Steps to reproduce:

@bsbechtel Imho it is very ok, that checkbox is toggled when item clicked - think about mobile apps, it is proper behavior, that is from the very beginning of ionic. But you can achieve what you need wrapping ion-checkbox in slotted div:

<div slot="start" style="position: relative"><ion-checkbox></ion-checkbox></div>

Thanks for the issue! This is the intended behavior for mobile devices to match the native behavior. However, as a workaround you could use the following: https://codepen.io/brandyscarney/pen/vYNeLzZ?editors=1100

ion-item {
  --background-hover: none;
  --background-activated: none;
  --ripple-color: transparent;
}

ion-checkbox {
  position: relative;
}

What this does:

• Removes the hover / activated states & ripple effect from item so it doesn't appear clickable
• Sets checkbox position to relative which will move the checkbox click to only appear over the checkbox itself (this is essentially what happens when a user adds multiple checkboxes in an item)

I'm going to mark this as a needs: design decision as we will need to discuss the API for disabling this behavior in the framework.

In my case the checkbox is only toggled on the first item on the ios style.
The second item it is only toggled when I tap on the checkbox (thats what i want).

I think both cases are valid but it should be consistent.
