Is there a way to list (within a callback) all the currently available ids in the app layout? For example if my app has three divs and all have ids getting a list with the three values.

A very simple way to do this is wrap everything you need in a div, and give it an id: `html.Div(id="stuff")`. Then just put it into whatever callback you want as state: `State("stuff", "children")`. The result will look something like this (here, a `dcc.Dropdown` within an `html.Td`):

And then you can access whatever you want, e.g.: `div["props"]["children"]["props"]["value"]`.

There are other ways to do this, but I’m not too sure since it’s been some time. I think it was something along these lines (one or more of them, all are worth looking into), on the app object (`app = dash.Dash`):

- `app.callback_map`
- `app.layout`
- `app._layout`
- `app. __dict__ `

Thanks! This is exactly what I needed.
