Best way to hide code cells?

[joaquinvanschoren]

Description

Is there an easy way to hide code cells in the generated RISE slides?

In the notebook version there are plugins to hide all code cells with the 'hide-input' tag, which also makes them invisible in the RISE slides.

I tried doing the same in jupyter lab. Eg. the jupyterlab-hide-code does hide the code cells in jupyter lab, but they are still visible in the jupyterlab-rise slides.

Is there a known solution on how to do this?

Reproduce

Create any notebook with code cells and set the 'hide-input' tag.
The code cells are not hidden in Jupyter Lab but not in the RISE slides, see screenshot:

I think it would be ideal if there were a hide_code boolean in the cell metadata which you could easily toggle with a dropdown in the Property Inspector similar to how you can already do with Slide Type - e.g.

{
    "trusted": true,
    "execution": {
        "iopub.status.busy": "2023-11-10T04:41:22.157874Z",
        "iopub.execute_input": "2023-11-10T04:41:22.158409Z",
        "iopub.status.idle": "2023-11-10T04:41:22.166432Z",
        "shell.execute_reply.started": "2023-11-10T04:41:22.158409Z",
        "shell.execute_reply": "2023-11-10T04:41:22.164817Z"
    },
    "editable": true,
    "slideshow": {
        "slide_type": "fragment",
        "hide_code": true
    },
    "tags": []
}

Hi! Any news on this?
I can't find any way to make this work, which is a pity because this tool is otherwise really neat.
