[jQuery] Collapsing margins vs. slideDown/slideUp

Hi jQuerians,
just wanted to let you know that if you want to use slideUp/slideDown on
an element, you have to avoid collapsing margins in some cases,
otherwise the effect will let the element jump on start/end.
Say you have two elements and you want to let the second element
slideUp/slideDown:

...

<ul>
<li>...</li>
</ul>
In my case the margin-bottom of

collapsed with margin-top of the <li>.
If you let the entire <ul> slideUp/slideDown the <li> elements will
jump... I assume that it is because some style (border?, padding?) is
set for the effect, that breaks the collapsing.
So to avoid that collapsing and assure a beauty effect, you can add a
padding for the <ul>:
padding: 1px 0 0;
Or rearrange the margins, so that there is no collapsing anyway.
Maybe someoneelse ran into that problem besides me...
Cheers
