bug(MatRipple): MatRipple can not be disabled for child components

[angelaki]

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

Description

I once opened this issue (#26656) and now coming back with another real-world-issue, that can't be solved neatly.

I have a selection with a ripple effect (the boxes in the screenshot) and some, optional, sub-options:

Now every time I hit a suboption the box' ripple effect shows up. Disabling it only on inner click and re-enabling it seams like some nasty timing problem (and even looks like [ripple gets removed on mouse down etc.]).

In my opinion there really is a need to be able to disabler the ripple effect for some boxes inside the ripple container. There should either be a directive for disabling it or to make things easy, like I suggested in my previous post, be able to switch from capture to bubbling so it can be disabled the vanilla Javascript way (stopPropagation).

Reproduction

Expected Behavior

Ripple should not show up on clicking some container's child elements.

Actual Behavior

Ripple cannot be disabled for some inner clicks.

Environment

• Angular: 18.0.1
• CDK/Material: 18.0.0

You can easily create your own directive to disable ripples for a whole subtree in the DOM:

import {MAT_RIPPLE_GLOBAL_OPTIONS} from '@angular/material/core';

@Directive({
  selector: '[disable-ripples]',
  standalone: true,
  providers: [
    {
      provide: MAT_RIPPLE_GLOBAL_OPTIONS,
      useValue: {
        disabled: true,
      },
    },
  ],
})
export class DisableRipples {}

This suggestion relys on the DI model? How would this work? I need to disable the parents ripple! When clicking the options, I do not want the box' ripple to be shown. Sure I could globaly disable it and only work with launch(), but ...

[crisbeto]

Ah I see, I thought you wanted to disable the ripples on all the children, not on the parent.

Hi @angelaki / @crisbeto, I have a similar scenario, there is a hyperlink inside mat-slide-toggle's label to open a dialog. Clicking on the hyperlink is triggering the ripple on the slide toggle.
Please let me know if you find any workaround.
