Here is a function which may be of interest. I have included some test
input data.
The data is not really nested-list because it doesn't have 'lft' and 'rgt'
fields.
Rather this assumes that you are using a simple parent_id field to build a
list suitable for superfish.
If you come up with anything interesting, please let me know.
def test_html_nodes(nodes,link_to_function='area'):
if not nodes:
nodes = [
{ 'id':1, 'parent_id':None, 'name':'a' },
{ 'id':2, 'parent_id':None, 'name':'b' },
{ 'id':3, 'parent_id':2, 'name':'c' },
{ 'id':4, 'parent_id':2, 'name':'d' },
{ 'id':5, 'parent_id':4, 'name':'e' },
{ 'id':6, 'parent_id':None, 'name':'f' }
]

output = ''
global count
count = 0
def build_node(node):
global output
li_id = ' id="%s"' % node['id']
output += '<li%s>'%li_id + \
str(A(node['name'],_href=URL(link_to_function,args=[node[
'id']])))
build_nodes(node['id'])
output += '</li>'
def build_nodes(node_parent_id):
global output
global count
count += 1
subnodes = [node for node in nodes if node['parent_id'] ==node_parent_id
]
if len(subnodes) > 0 :
cl = ' class="sf-menu sf-vertical sf-js-enabled sf-shadow"' ifcount
==1 else ''
output += '<ul%s>' % cl
[build_node(subnode) for subnode in subnodes]
output += '</ul>'
build_nodes(None) # Pass in None as a parent id to start with top level

return output
