Attribute types: File attachment
Lumeer lets you upload file attachments and save them as attribute (column) values.
After you set the attribute type to File attachment, double-click on the cell and click on Add file. A standard file upload dialog will appear.
When the file is uploaded, you can see an icon depending on the type of file.
If you click on the icon, the download starts. If you click anywhere in the cell, file name is displayed, and it can be removed by clicking on red trash icon. You can even add more files to the same cell.
