To create new Elements, click the Add () button. See Creating Elements for more details.
To delete existing custom Elements, select the Element(s) using the checkbox selector and click the Delete () button.
System (i.e., out-of-the-box) Elements cannot be edited or deleted. Copy a system Element if you would like to create a custom Element based on it.
To duplicate an existing Element, click the Actions () button and select Copy. The duplicated Element can be deleted or edited just like any other custom Element.
To export an Element, click the Actions () button for the Element and select Export.
To import an Element, click the Actions () button in the top corner of the screen (next to the Global Menu icon). Click Import and browse to the Element’s JSON file.
The Element schema can change. If the schema changes between Liferay versions, importing the older Element’s JSON may fail.
