I am facing an issue with a nested modal where the backdrop hangs behind the already opened modal. I have gone through the documentation and found ModalBackdropComponent with a selector of bs-modal-backdrop. However, I am unsure about how to specify the position of the backdrop to resolve this problem. I am not sure if this is due to a z-index conflict or if there is a specific placement required for the backdrop.
Encountered the same issue today and struggled to find a solution by defining my own instance of the bs-modal-backdrop component. What worked for me was setting [config]="{ backdrop: false }" on the bsModal element of the child modal to disable the default backdrop. Then, I inserted a new element like this:
<div class="modal-backdrop fade in" (click)="modal.hide()"></div>
This new element was added as the first child inside the child modal bsModal element. Assuming you have defined the modal property as #modal="bs-modal" or something similar. Another approach could involve calling a method on your component with the click handler.
Additionally, it may be necessary to assign a z-index of 1050 or above to the .modal-dialog element (a sibling of the new .modal-backgrop element).
When using ngx-bootstrap, there is limited control over the classes assigned to the modal container and backdrop elements. It seems impossible to insert a new element as a sibling of the .modal-dialog.
However, it is possible to style the nested/child modal containers individually. These containers are added to the DOM sequentially, allowing for CSS selectors such as :nth-of-type to target specific modal containers and customize their appearance, such as adjusting the background to create a faded effect.
.modal-container:nth-of-type(2) {
background: rgba(0, 0, 0, 0.5);
}
Within the worldwide CSS file (styles.css):
modal-container+modal-container {
background: rgba(0, 0, 0, 0.5);
}
