Removing Widgets in Databricks
To remove widgets in Databricks, you can use either the UI or the Databricks widget API. Here are the steps for both methods:
Removing Widgets via UI
1. Open your Databricks notebook and locate the widget you want to remove.
2. Click on the kebab menu (three dots) next to the widget.
3. Select “Remove” from the dropdown menu.
Removing Widgets Programmatically
To remove a widget programmatically, you can use the dbutils.widgets.remove() method. This method takes the name of the widget as an argument.
For example, to remove a widget named “my_widget”, you would use the following code:
