The PopupMenu menu element defines a popup menu in a TextField or TextBox element.  The popup menu is invoked by right-clicking the text field or box.

A PopupMenu element can contain any number of Menu, MenuItem, or MenuSeparator elements.

A PopupMenu element can be contained in a Maplet, TextBox, or TextField element.

The following table describes the control and use of the PopupMenu element options.

An x in the I column indicates that the option can be initialized, that is, specified in the calling sequence (element definition).

An x in the R column indicates that the option is required in the calling sequence.

An x in the G column indicates that the option can be read, that is, retrieved by using the Get tool.

An x in the S column indicates that the option can be written, that is, set by using the SetOption element or the Set tool.

The opts argument can contain one or more of the following equations that set Maplet application options.

reference = name or string

A reference to the PopupMenu element.

If the reference is specified by both an index, for example, PopupMenu[refID], and a reference in the calling sequence, the index reference takes precedence.

visible = true or false

Whether the menu is visible to the user.  By default, the value is true.
