Feature Request

Ionic version:

[x] 4.x

Describe the Feature Request

Implement an indeterminate state for the ion-checkbox component. We need this for a nested checkbox tree structure.

different checkbox states

Describe Preferred Solution

The easiest way is probably to add an indeterminate prop, because the indeterminate state is visual only and doesn't effect the actual value of the checkbox.

Related Code

export class NestedCheckboxes {
  render = () => [
    <ion-checkbox indeterminate={true} />
    <ion-checkbox onClick={e => ( = true)} />

Additional Context

Article on CSS Tricks.

#11601 is the same (closed) request, just linking here for context.

I will try make a PR for this later today.

feat(checkbox): implement indeterminate state
This adds an `indeterminate` prop to the `ion-checkbox` component,
which visually renders the checkbox with a dash to indicate an
indeterminate state.

Closes ionic-team#16943.
