To embed an external iframe in a Superset dashboard, you need to adjust the
HTML sanitization settings. Here's a solution based on a similar discussion:
1. **Modify `superset_config.py`:** You need to extend the HTML sanitization
schema to allow iframes. Add the following configuration to your
`superset_config.py`:
```python
HTML_SANITIZATION_SCHEMA_EXTENSIONS = {
"attributes": {
"*": ["style", "className"],
"iframe": ["src"]
},
"tagNames": ["style", "iframe"],
}
```
2. **Update Content Security Policy (CSP):** Specify the allowed sources for
iframes in the CSP. Add the following to your configuration:
```python
TALISMAN_CONFIG = {
"content_security_policy": {
"frame-src": [
"'self'",
"https://example.com";,
],
}
}
```
These changes will allow you to use iframes in your dashboard. Make sure to
restart your Superset server after making these changes to apply them
