ng-bootstrap Modal size

Question

What is the best way to set/override a custom width for a modal?

It seems ng-bootstrap currently supports

size: \'sm\' | \'lg\'

Answer 1

add following css in style.css file.

.xlModal > .modal-dialog {
    max-width: 1490px !important;
    min-width: 971px !important;   
    width: 95% !important;
}

Note : we can replace .xlModal with any name.

open modal with new created style.

this.modalService.open(content,{windowClass:"xlModal"});

Answer 2

I found this as a good solution.

this.modalService.open(MyComponent, { windowClass: 'my-class'});

ng-deep “shadow-piercing” descendant combinator can be used to force a style down through the child component tree into all the child component views. In this case modal-dialog class.

::ng-deep .my-class .modal-dialog { 
     max-width: 80%;
     width: 80%;
}

You could wrap it into a function like

component.ts

// accepts 'sm', 'md' or 'lg' as argument.
// default argument 'md'
public openModal( dialogSize: 'sm' | 'md' | 'lg' = 'md'): void {
  let modalOptions = {};
  if (dialogSize === 'sm' || dialogSize === 'lg') {
    modalOptions = { size: dialogSize };
  } else {
    modalOptions = { windowClass: 'md-class' };
  }
  this.modalService.open(ConfirmationDialogComponent, modalOptions);
}

component.css

::ng-deep .md-class .modal-dialog { 
    max-width: 80%;
    width: 80%;
}

And call it like,

openModal(); //argument 'md'
openModal('sm'); //argument 'sm'
openModal('md'); //argument 'md'
openModal('lg'); //argument 'lg'

Answer 4

When you don't specify the size, the default value use $modal-md (500px).

All the 3 modals sm, md and lg are responsive and will display on full width (with borders) on mobile.

If you really want a new size, you can use a custom size:

this.modalService.open(MyModalComponent, { size: <any>'xl' });

With a css for this class:

.modal-xl {
  max-width: 1000px;
}

EDIT: the xl size is now a standard size so the CSS.

Answer 5

Add a argument class: 'modal-lg'

open() {
        const modalRef = this.modalService.open(ModelComponent, { class: 'modal-lg', backdrop: 'static' });
    }

}

Answer 6

Try like this :

import { NgbModal, NgbActiveModal } from '@ng-bootstrap/ng-bootstrap';
import { ModelComponent } from './model.component';

export class Component {

    constructor(private modalService: NgbModal) {}

    open() {
        const modalRef = this.modalService.open(ModelComponent, { size: 'lg', backdrop: 'static' });
    }

}
