There was a problem implementing Notification using dash_martine_components

Dash Python

You are using dash_mantine_components

The problem is that the callback should be executed as much as I want to list.
Notification occurs only once per click on .

What I want is for notifications to occur at the same time as the number of example_list in the code.
(Notification expression as many as the number of example_list when clicking the button, so that the contents of the example_list can be seen in Notification)

I don’t know how to loopback, so I can’t implement it.

Please give me a good opinion

Is this the right way to do it?

Hello @ShinDongGeun,

Right now, you are overwriting the div with the new child.

If you want to stack, you need to grab the state of the children of caveat-container. And then add your last child to the end through an append statement.
