Dave, nice idea. i am not sure that this should be standard though, since the page templates of xowiki can do it very similar things (current shortcoming: content of template variables can only be inserted via plain text fields). actually, it won't be hard to let an admin specify for what fields what kind of input widget can be used, but i have some other real work to do... it will come sooner or later.
It is nice see that some little work can make people happy.
The original code listed all catagories from all trees in a long page, which is not optimal. i have now updated the category plugin in CVS to handle multiple category trees. one can now specify "tree_name" as a parameter (see below) to display only the wanted trees (the value is a match pattern). if "no_tree_name" is set, the tree_name is not displayed.
This is a repository with many nice examples of XoWiki pages.>left-col<<
