Is it acceptable to open a modal popup on top of another modal popup?

Using a modal on top of another modal is a big red flag that something broke down in your workflow. If your workflow requires a second modal, you probably have some bigger issues with complexity within your modal.

What can I use instead of modal?

Consider Nonmodal Dialogs Instead

In situations where the task is not critical, a nonmodal dialog might be appropriate. Nonmodal dialogs are less offensive than modal ones because they allow users to continue their activity and ignore them if they are irrelevant.

What is the difference between popup and modal?

Modals, like pop-ups, are components that pop up on a user's screen. The key difference, however, is that the user would have initiated the action as part of their journey. Modals are used for specific workflows such as adding users, deleting content, sharing content, adding content, and more.

What is the difference between popover and pop up?
