Deleting Widgets in Databricks Notebooks
To delete widgets in a Databricks notebook, you can use the Databricks Utilities (dbutils) API. This API provides methods to remove individual widgets or all widgets at once.
Removing a Single Widget: You can remove a specific widget by using the dbutils.widgets.remove("widget_name") method. Replace “widget_name” with the actual name of the widget you want to remove.
Removing All Widgets: To remove all widgets from the notebook, use the dbutils.widgets.removeAll() method.
These commands can be executed in Python, Scala, or R notebooks. For SQL notebooks, you can use the REMOVE WIDGET widget_name command to remove a single widget.
