How to SNAP top and down menu elements?

[listy]

On the last changes I committed, I had started to reorganize the TaskElementWdg, breaking it into some component functions so that the code is much more understandable.  In doing so, I also eliminated a lot of redundant (and even tried a bit of JSX, which is still highly experimental ... more on that sometime later in another post).

I haven't made anything dynamic yet.  Are any of those lists in the drop downs huge?

There is another thing i wanted to tell. I don't know how it's made in web and js, but with the QT i made on demand loading, so i don't have to cache all images before show all elements, but make them just before showing.
In this example, previews and other controls are created when user scrolls items:



(Sorry for showcasing T-H all the time, but this tool was made to cover things i wanted to see in tactic)
