Topic: mdb-date-picker how to set focus on something within the date picker modal

Using MDBootstrap 4 Datepicker control within an Angular 10 application, I am attempting to set focus to something/anything within the date picker modal window after it loads so the user has a good keyboard navigation experience. I am currently experiencing a behavior that allows the user to keyboard tab navigate on the form in the background of the datepicker modal after the it loads. I want to explicitly set focus to something in the date picker modal to get around this problem. I have not found a solution to this yet.

The MDBDatePickerComponent has a property called "divFocus" of type "any" but I have found no documentation of what it is used for. It looks promising but I don't even know what it is suppose to be used for due to lack of documentation. Perhaps there is another way to accomplish this.

I have also tried something like this with no luck thus far....

@ViewChild('datePicker', { static: true }) initialFocus: ElementRef; ... this.initialFocus.nativeElement.focus();

Resources (screenshots, code snippets etc.)

Please insert min. 20 characters.

Here is an example showing how you can focus left arrow button after modal is opened:

HTML:

<mdb-date-picker (calendarToggle)="onToggle($event)"></mdb-date-picker>

TS:

  onToggle(event: any) {
    // event fired when modal is opened
    if (event === 1) {
      setTimeout(() => {
        const prevArrow = document.querySelector('.picker__nav--prev') as HTMLElement;
        prevArrow?.focus();
      }, 0);
    }
  }

This component should have focus trapped inside the picker container and first focusable element should be focused by default. I added this task to our to-do list and we will fix that on our end.

Thanks for the response and answer. This answers my question. I am a little curious still as to what the "divFocus" property is suppose to be used for on the md-date-picker. Do you have any information on that? I didn't find anything in the docs about what it is used for. Thanks in advance.

@matt5733 This variable is a part of component private API, it was used to get access to the element from the component template. This is not something you should use or modify on your end.
