How to call Custom Widget

Please teach me.
How can I call my own custom widget from docs.getgrist.com?
Also, how can I call my own custom widget from grist-electron?
Thank you.

Hi there,

First, you’ll need to host your widget somewhere. We use GitHub Pages and it creates a URL for the repository.

Then, when you’re configuring a custom widget either at docs.getgrist.com or when using Grist-Electron, you’ll enter the URL rather than selecting a pre-made custom widget.

For example, I have a custom widget to view URLs, hosted on my personal github.io repository.

The URL for this widget would be https://nataliemisasi.github.io/URL_viewer

If I enter this as the custom URL for the widget, I can then configure the widget and then view the website at the URL listed.

Thanks,
Natalie

Thank you for reply.
docs.getgrist.com worked fine.
But Grist-Electron is not good.
