Allow Multiple Values
For the Allow Multiple Values option, you set
whether the users can choose multiple terms. You should not select this
option if you want the users to be able to select just a single term.
Display Value
The Display Value option sets how the terms
will be displayed to a user viewing the properties of the file or list
item. Because the terms might be hierarchical, showing just the value of
the term (the term label) can lead to confusion if two terms have the
same label but are under different hierarchies.
For example, if you have a term set that has
mobile phones under the manufacturers, and if two different
manufacturers have the same name for a mobile phone, you will not know
by looking at the label which mobile phone it is unless you select
Display the Entire Path to the Term in the Field, which displays the
entire hierarchy as the value of the column.
Term Set Settings
As mentioned earlier, you can connect a column
to an existing term set by using the Use a Managed Term Set option.
This option allows you to select the existing term set from the box
under it, as shown in Figure 32.
FIGURE 32 Selecting an existing term set.
If you want to create your own new term set
instead, you select the Customize Your Term Set option. This enables you
to create the term set in the box under that option. By default, when
you select the Customize Your Term Set option, a new term set is added
with the label Untitled. You can rename the term set by clicking on it
once and typing the new name. To create terms in the term set, you open
the drop-down menu for the term set (hover with the mouse over the name
of the term set, and then open the menu that appears) and click Create
Term, as shown in Figure 33.
FIGURE 33 Creating a new term in a custom term set.
Clicking on the Create Term option creates a
new term without a label (name), and you can then give it a name. You
can then open the menu for that term and either create terms under it
(using the Create Term option), move it, or delete it.
A more advanced way to manage the term set is
to click the Edit Using Term Set Manager link at the bottom of the
configuration options box. This opens a new page, shown in Figure 34,
that has more options for managing the term set, including the
description for the term set, an ability to lock down the term set,
different sorting options, and more.
