A spreadsheet layout that allows you to edit item fields directly inline, just like in a spreadsheet.
To install the extension, take a look at the Official Guide.
Once installed, go to your collection page, on the Layout Options tab in the sidebar, select Spreadsheet from the Layout drop-down list.
Save: If the Automatic checkbox is checked, your changes will be saved automatically. If it is unchecked you will have to manually press the Save button that appears on the top right corner (or use the keyboard shortcut [cmd] + [s]) to save your changes.
Spacing: Change the spacing of the spreadsheet rows as you would in the default table layout.
Click a cell within the collection spreadsheet and press [Enter] or Double-click to enter the field and make your change. When you exit the cell by clicking outside it or pressing [Escape], the field value is updated if you have autosave enabled. Otherwise, the cell appears as edited. You can use the arrow keys to navigate through the cells. You can add fields/columns using the +-button in the upper right corner of the collection spreadsheet, just like in the default table layout.
Types: string, text, bigInteger, integer, float, decimal, boolean, dateTime, date, time, timestamp.
Interfaces: boolean, datetime, input, input-autocomplete-api, select-color, select-dropdown, select-icon, slider.
