|

|

156 There are two known issues with YAHOO.widget.Overlay (the superclass class of
|
|
157 Menu) that manifest in Gecko-based browsers on Mac OS X:
|
|
158
|
|
159 1) Elements with scrollbars will poke through Overlay instances floating
|
|
160 above them.
|
|
161
|
|
162 2) An Overlay's scrollbars and the scrollbars of its child nodes remain
|
|
163 visible when the Overlay is hidden.
|
|
164
|
|
165 To fix these bugs in Menu (a subclass of YAHOO.widget.Overlay):
|
|
166
|
|
167 1) The "overflow" property of a Menu instance's shadow element and child
|
|
168 nodes is toggled between "hidden" and "auto" (through the application
|
|
169 and removal of the "hide-scrollbars" and "show-scrollbars" CSS classes)
|
|
170 as its "visibility" configuration property is toggled between
|
|
171 "false" and "true."
|
|
172
|
|
173 2) The "display" property of <select> elements that are child nodes of the
|
|
174 Menu instance's root element is set to "none" when it is hidden.
|
|
175
|
|
176 PLEASE NOTE:
|
|
177
|
|
178 1) The "hide-scrollbars" and "show-scrollbars" CSS classes classes are
|
|
179 applied only for Gecko on Mac OS X and are added/removed to/from the
|
|
180 Overlay's root HTML element (DIV) via the "hideMacGeckoScrollbars" and
|
|
181 "showMacGeckoScrollbars" methods of YAHOO.widget.Overlay.
|
|
182
|
|
183 2) There may be instances where the CSS for a web page or application
|
|
184 contains style rules whose specificity override the rules implemented by
|
|
185 the Menu CSS files to fix this bug. In such cases, is necessary to
|
|
186 leverage the provided "hide-scrollbars" and "show-scrollbars" classes to
|
|
187 write custom style rules to guard against this bug.

|
