I don’t understand how am I rewriting the buttons? I am just removing one child and giving the remaining chidren. Does this rewrite the button?
Yes, it does. It may not look like it, as if you inspect children, you will see a nested dictionary with the JSON representation of the components defined in the dbc.Container, but effectively you are just rewriting them.
Dash does not support partial updates of props (props being the “parameters” you can pass to a component when initialising it or in a callback), so I don’t think there is a better way to do what you are doing. You just have to work with it and be aware that the callbacks depending on components being rewritten will be triggered again.
