How to Edit a List Item

Sign in or go to the 'Organization and Projects' page.

Click on the document where you want to edit an item.

From here there are two ways to go.

Edit the whole item at once

Click the item menu button and select the Edit Item menu item. Notice that the button only appears when the mouse is over the item row.

You will then see the Item Dialog where you can change the item values.

Edit each value separately.

Click on the edit button in the cell which you want to edit.

What happens next depends on the type of column and how it is formatted. Either

a small dialog box will appear where you can change text or numerical values; or
a drop down menu of all possible values will appear where you can select a new value; or
in the case of a flag the value will just switch from the current value to the other possible value.
