UI Default effects

UI Default effects

Hello guys, im in doubt about which effects can be used with the widgets without downloading the effects core.

If i download the datepicker widget, i can use the effects "slideDown", "fadeIn" and "show" (with the method "showAnim").

Here is what the documentation says about the showAnim method:

"Set the name of the animation used to show/hide the datepicker. Use 'show' (the default), 'slideDown', 'fadeIn', any of the show/hide jQuery UI effects, or '' for no animation.".

However, these effects does not work if i use them with the dialog widget.

Is it a bug of dialog widget or these effects can be used only with the datepicker?

Kind regards and thanks for advance.
