PluggableListMorph in Morphic, PluggableListView in MVC), which then arrives as "someMenu" in your model's menu-construction method. That "someMenu" will then be a MenuMorph (in Morphic) or CustomMenu (in MVC). See above for that case. :-)<br>

On my list of things to attack one day is cleaning up the horrendous mess of menu building via toolbuilder. Maybe by the time I get to it somebody else will have solved it for me.<br>

... which is possibly the nastiest way one could do it. If you have to have menus with more than ~9 items, a well thought out hierarchical menu is the least awful approach. If you arrange for it to work well then it is possible to make even complex hierarchies
seem natural; see for example, how RISC OS does the job.<br>
