To access the Attribute List Management, head to the Admin Center and then choose Attribute List Management, which is within the Administrative Lists section. The Attribute List Management window will allow you to choose a data layer that you wish to access and then each individual attribute from said data layer.
About Attribute List Management
Once you choose an attribute, you will see its list values.
The first column is the List Value, which is the text that will be appear in the attribute list.
The next column is Sort Value, containing numbers that determine how the list values will be sorted when displaying the list. As a rule of thumb, the lowest number will appear first in the list and the highest number will appear last in the list.
The sort values will only take effect if the attribute’s List Sort Order is set to ‘Customized’.
For most attributes, the last column will be Usage Count. This shows how many times each list value is used. This total number of uses for each list value and can be helpful when determining if an attribute can be safely removed or not.
An exception to that is when you are viewing the Condition attribute list. In that case, there will also be a Rating column. Condition attributes have an iTree rating attached to the tree condition values, which is what would be entered in the Rating field.
Lastly, Actions is where you can A: edit a list value, or B: delete a list value.
Adding a List Value
To add a list value, navigate to the attribute you want to add the list value to like described above, and scroll to the bottom of the window to find the green '+' button.
This will bring up the Add List Value form, where you will fill out the fields like List Value and Sort Value for most attributes, as well as Rating for Condition attributes only.
Click Save when you’re done filling out the form and you will have a new value in your attribute list!
