I'm talking about a 'dropdown' optional feature which could be enabled on 'Category' and 'Archive' widgets.
while it could be a rather useful feature as it saves some space on sidebar, it has several problems:
* next, a current approach used ('onchange' event JS handler) makes this widget unusable for keyboard (visually impaired) users and their accesibility assisting software (usually based on win IE, like 'JAWS').
see also http://html.cita.uiuc.edu/auto/onchange.php for example (but mind both their "solution" seem to me rather far from the best practices);
* and finally, whereas a drop-down combo list-box is handy UI element (as it hides its content) I'd love to see hiearchical category widget implemented as DHTM/CSS expandable tree which fallback gracefully down to simple unordered list like in the http://www.scss.com.au/family/andrew/webdesign/explorertree/ (look for "Google" menu tree example on this page).
thank you for reading.
