slideToggle not working with height: auto and all floating elements

[capsule]

Hi,

If you apply a slideToggle() effect on an element which height is defined as "auto" in your CSS file and all contained elements are floating (in my case, one element floating left and another floating right), the slideDown works but not the slideUp (it disappear and then slideDown again). I guess this is because the container on which I try to apply the effect has no height due to the floating only elements.

If I define a fixed height on the container, the toggle effect works.

Btw, this is affecting the "slideUp" effect as well (not working, for the same reason I guess).

Maybe jQuery should calculate the height of the container based on its children's height?

HTH, Regards.

I've found similar behaviour when applying slideUp/slideDown effects to block elements floated:

if element is directly floated (I mean, not inheriting floating from ancestor element), slideUp/slideDown effects only hide/show the element, but the animation is not shown.

if the floating is moved upside to an ancestor slideUp/slideDown works fine.

I hope it helps to track and fix this problem.

I don't think this is something we want to change. There are many resources for doing clearfixes and jQuery is correctly animating the height of 0.

A similar behavior occurs when using min-height instead of height. The target div just appears and disappears without showing the sliding effect.
