To classify more than two documents at the same time within the repository, you must follow the following instructions:
Go to the main menu of the platform on the left side and click on documents.
Select the documents you want to classify.
Go to the upper right corner and click on more actions (three dots).
A window will open where on the left side you will see the selected documents and on the right side you will see the attributes menu.
Classify documents under attributes.
Click save, close the view.
Refresh the repository and you will see the selected documents sorted by attributes.
Note: You must bear in mind that this action is recommended only for documents that need to be classified under the same attributes, since you cannot classify documents with different attributes.
