These attributes are ignored if any either the prevpage (5.2.6.4), or nextpage attributes are present.
The treeselect, treefold, and treeellipsis attributes generate an href (5.2.6.2) attribute that respectively select, open/close, or expand the ellipsis of an <al-tree> (5.3.10) node via a LazyTreeIterator (5.3.10.8) or EllipsisTreeIterator (5.3.10.9) iterator.
Refer to the <al-input> tag for more information on how to use these attributes (5.2.2.10).
If the node (5.2.6.3) attribute if it is present it defines the node to operate upon. Otherwise the node operated upon is the current value of the LazyTreeIterator iterator.
The attribute value specifies the name of the LazyTreeIterator iterator.
The generated href attribute is of the form current_url?name,iter,alias=1 where current_url is the path component returned from the Python urlparse.urlparse() function (via the execution context current_url() method), name is either treeselect, treefold or treeellipsis, iter is the specified iterator, and alias is the values returned by the albatross_alias() method of the specified node.
