Thank you Espen, looking at that product could help me to improve the code I already have. But, as I just replied to Nathan Van Gheem, my question really intended to be whether it would be convenient to use the KSS framework in order to get a more modular and "standard" architecture.

I think there is a navigation product that does something similar (expanding folders). if these data are separate data, you might want to take a look at the code there (or maybe its possible to use it) Den 12. feb. 2009 kl. 01.57 skrev Giovanni Toffoli: In a product, I have a portlet providing a tree-like visualization of a taxonomic data structure (say, a thesaurus). A number of tree manipulation functions (e.g. sub-tree expanding and collapsing) are implemented with ad-hoc AJAX programming that I did in the Plone 2.1 version of said product. Those functions still work unchanged in the porting to Plone 3 that I'm doing, although I plan to re-implementing them using KSS. Moreover - the tree in the portlet is included in an HTML form - there is a checkbox beside each visible node in the tree, so that the user can select a subset of the nodes by checking the associated boxes. Here is may use case: in the content area of the page, as a separate HTML form, I have a search form for searching Plone contents; the search should take into account: a) the context b) obviously, the values that the user puts inside the input controls of the search form c) the tree nodes selected (checked) in the portlet. In the 2.1 version of the product, when the "search" button was pressed, I managed to get the current node selection by doing a horrible customization of the main template: the tree appeared to be inside a portlet, but in fact it was inside the same HTML form as the (other) input controls of the search form. In the Plone 3 version, where the tree is inside a true portlet, and a separate HTML form, which strategy would you suggest to be able to exploit the node selection in the search? 1) use KSS to build incrementally a server-side image of the current selection 2) associate a KSS event to the pressing of the "search" button; but in this case should I define an ad hoc client-side command and implement it as a plugin ? 3) other (please specify). Thank you very much for any advice.
