Re: [Trinidad] which component for a dropdown menu

[Renzo Tomaselli]

Steve,     many thanks, now it's clear. I guess I went through similar troubles while implementing my own TreeModel to get a lazy-loading and paged tr:tree, but finally it works fine. Concerning the dropdown menu I will likely pick up components from Tomahawk. -- Renzo [EMAIL PROTECTED] wrote: There is some confusion around the MenuModel. I have tried to implement the MenuModel myself (without using the supplied wrapper) and I can tell you it is not straight forward to do. This is one part of Trinidad that needs to change because this model is too tightly coupled with Oracles database and cursor technology that I have never bother to learn. I do not think the "model" is very clean. While the MenuModel itself can be nested, the af:menuBar can only show ONE LEVEL of that model. This is where the startDepth comes into play. It starts at 0 and this would be the root. If you want to show next level down you set the depth to 1, etc. Very confusing, basically showing each leaf of the tree. So this is mis-leading. Basically there is one model and each of the component types "renders" it differently. If you want a _javascript_ed drop-down menu then you will have to go else where for that type of control. While a "nice to have" feature I think you can easily design around it. You could put a second menu bar below the first, point to the same model, but set the startLevel to 1, visible if an item is selected in top menu. Its not a drop down but has same effect, some might actually prefer.

The MenuModel can be nested by definition. Furthermore ADF documentation at http://www.oracle.com/technology/products/jdev/htdocs/partners/addins/exchange/jsf/doc/tagdoc/core/imageIndex.html seems to deal with multilevel menus in the description of af:menuBar, which should become a tr:navigationPane. But I cannot find any example around - either for ADF or for Trinidad - dealing with such issue. -- Renzo [EMAIL PROTECTED] wrote: You are correct this type of menu does not exist in Trinidad or ADF. When needed I use the MenuTree but this is not horizontal.

I know that MenuModel is used almost everywhere for dynamic contents - I used it succesfully for tree and navigationPane. I guess that the latter might be a menu (as bar ? as buttons ?) but can it be dropdown ? With further levels ? There is no such kind of menu in the example set. Some appear in the Adf documentation, but component renaming/replacement makes it hard to guess. Even more, the Trinidad developers pages refers to navigation by means of a NavigationLevel component, which seems unexisting. Thanks for any hint -- Renzo
