If a collection is selected and opened in a tab, there are 3 variants to delete documents.
Single selection
In all three available views of documents, there is a button or an icon to delete a single record. After clicking the button and confirming a security query the document is deleted and the view is updated.
Multiple selection
In table view there is also the possibility to select the checkboxes next to each document or to select all records with the checkbox "Select All" in the table header. The button with the bin icon will appear in the toolbar. After confirming the security query, the documents are deleted and the number of deleted items will be shown in a on-screen message.
