[SOLVED] Mat-datepicker-toggle showing behind modal

Mat-datepicker-toggle showing behind modal

Helloo, I have a problem on my view using angular 4 and bootstrap 4. When I click on open to show calendar. It's showing behind my modal. I want to change z-index on its class but i don't have acces to the class because it's auto-generated. How can i fix the probleme? enter image description here This is my code. Thanks in advance.

Solution

The issue is that bootstrap-modal sets z-index:1050

.modal {
    position: fixed;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
    z-index: 1050;
    display: none;
    overflow: hidden;
    -webkit-overflow-scrolling: touch;
    outline: 0;
}

The material date picker sets z-index: 1000 when the ckd-overlay-pane is created

.cdk-overlay-pane {
    position: absolute;
    pointer-events: auto;
    box-sizing: border-box;
    z-index: 1000;
    display: flex;
    max-width: 100%;
    max-height: 100%;
}

Adding this to your component style sheet should do the trick... but this will apply to all date-pickers in your entire project.

You will need to include a custom class identifier to make this specific to your modal date-picker if you only want to change that one.
```
::ng-deep .cdk-overlay-container mat-datepicker-content{
  z-index:2000;
}
```

Please reference the answer on this SO question for why using ::ng-deep is ok until further notice.
