How to Access
- Click the Versions button on the toolbar while editing the item.
In the table containing Items these are the different columns as shown below. Click on the column heading to sort the list by that column's value.
- Checkbox. Check this box to select one or more items. To select all items, check the box in the column heading.Note: Many toolbar actions can work with multiple items.
- Date. The time and date that the version was saved. Clicking on this link opens the Preview of that version in a window. Note that one of the dates will be followed by a star symbol. This indicates that this is the version that is currently saved and being edited.
- Version Note. When you edit an item, you have the option to enter in a Version Note. This can be used to help you remember which version has which information. If you entered a Version Note before saving the item, it will show in this column.
- Keep Forever. This column shows whether you have marked the version as Keep Forever. Normally, each version will be retained according to the settings in the component options screen. The default settings are to keep a maximum of 10 prior versions for an item. In this case, when you save an item that already has 10 saved versions, the oldest version is deleted. If a version is marked as Keep Forever, it will not be counted as one of the saved versions and will not be deleted when the maximum number is reached. To toggle the Keep Forever on or off, check the version's check box and then click the Keep On/Off button in the toolbar.
- Author. The user who saved this version.
- Character Count. The total characters saved in this version. Note that this includes the database column names as well as the actual characters typed in.
