1861    
1862    Display a selection tree.
1863    
1864    This method creates the HTML for a tree selection control. The tree is implemented as a set of
1865    nested HTML unordered lists. Each selectable element of the tree will contain a radio button. In
1866    addition, some of the tree nodes can contain hyperlinks.
1867    
1868    The tree itself is passed in as a multi-level list containing node names followed by
1869    contents. Each content element is a reference to a similar list. The first element of
1870    each list may be a hash reference. If so, it should contain one or both of the following
1871    keys.
1872    
1873    =over 4
1874    
1875    =item link
1876    
1877    The navigation URL to be popped up if the user clicks on the node name.
1878    
1879    =item value
1880    
1881    The form value to be returned if the user selects the tree node.
1882    
1883    =back
1884    
1885    The presence of a C<link> key indicates the node name will be hyperlinked. The presence of
1886    a C<value> key indicates the node name will have a radio button. If a node has no children,
1887    you may pass it a hash reference instead of a list reference.
1888    
1889    The following example shows the hash for a three-level tree with links on the second level and
1890    radio buttons on the third.
1891

1893                Entities => [

1903                ]
1904            ]
1905        ]
1906    
1907    Note how each leaf of the tree has a hash reference for its value, while the branch nodes
1908    all have list references.
1909    
1910    This next example shows how to set up a taxonomy selection field. The value returned
1911    by the tree control will be the taxonomy string for the selected node ready for use
1912    in a LIKE-style SQL filter. Only the single branch ending in campylobacter is shown for
1913    reasons of space.

1940    This method of tree storage allows the caller to control the order in which the tree nodes
1941    are displayed and to completely control value selection and use of hyperlinks. It is, however
1942    a bit complicated. Eventually, tree-building classes will be provided to simplify things.
1943    
1944    The parameters to this method are as follows.
1945    
1946    =over 4
1947    
1948    =item cgi
1949    
1950    CGI object used to generate the HTML.
1951    
1952    =item tree
1953    
1954    Reference to a hash describing a tree. See the description above.
1955    
1956    =item options
1957    
1958    Hash containing options for the tree display.
1959    
1960    =back
1961    
1962    The allowable options are as follows
1963    
1964    =over 4
1965    
1966    =item nodeImageClosed
1967    
1968    URL of the image to display next to the tree nodes when they are collapsed. Clicking
1969    on the image will expand a section of the tree. The default is C<../FIG/Html/plus.gif>.
1970    
1971    =item nodeImageOpen
1972    
1973    URL of the image to display next to the tree nodes when they are expanded. Clicking
1974    on the image will collapse a section of the tree. The default is C<../FIG/Html/minus.gif>.
1975    
1976    =item style
1977    
1978    Style to use for the tree. The default is C<tree>. Because the tree style is implemented
1979    as nested lists, the key components of this style are the definitions for the C<ul> and
1980    C<li> tags. The default style file contains the following definitions.
1981    
1982        .tree ul {
1983           margin-left: 0; padding-left: 22px
1984        }
1985        .tree li {
1986            list-style-type: none;
1987        }
1988    
1989    The default image is 22 pixels wide, so in the above scheme each tree level is indented from its
1990    parent by the width of the node image. This use of styles limits the things we can do in formatting
1991    the tree, but it has the advantage of vastly simplifying the tree creation.
1992    
1993    =item name
1994    
1995    Field name to give to the radio buttons in the tree. The default is C<selection>.
1996

1998    
1999    Frame target for links. The default is C<_self>.
