I've created a test html page to illustrated this. When the page loads, the menus behave correctly. The menus are created using <ul> and CSS styling to hide the sub-menus. When you hover over the <li> element, then the sub-menus appear. After the page loads the menus work as expected. When moving the mouse over the menu item, the sub-menus appear. However, if you scroll up a little, then you find that the lower sub-menus begin to be clipped? If you scroll too much, then the entire sub-menu is clipped and is invisible. It must still be at the correct location because the links in the sub-menus are still active. You just can't see the submenu? The z-index is set to 100 to make sure the sub-menus should always be drawn above the text. With the latest builds some draw clipping error appears to have crept in. 39811 1 12019 Hanspeterschaub 2006-12-25 10:08:11 -0800 Created attachment 12019 test file with simple dynamic menu on top left of page. To try out this test page, hover the mouse over the single menu item on the top left of the screen. All four sub-menus should appear. If you scroll the page up a little, the menu should not change location (position:fixed). Now, if you mouse over the menu item, the sub-menus will appear clipped or be entirely invisible, depending on how much you scrolled. 39809 2 Hanspeterschaub 2006-12-25 10:12:33 -0800 I just did another test. If the <ul> menu structure is not fixed to the screen (position:fixed), then the clipping issues do not appear? This seems to be tied to using position:fixed. 39804 3 mitz 2006-12-25 12:10:07 -0800 *** This bug has been marked as a duplicate of 11452 *** 12019 2006-12-25 10:08:11 -0800 2006-12-25 10:08:11 -0800 test file with simple dynamic menu on top left of page. test.html text/html 1560 Hanspeterschaub PCFET0NUWVBFIGh0bWwKUFVCTElDICItLy9XM0MvL0RURCBYSFRNTCAxLjAgU3RyaWN0Ly9FTiIg CiJodHRwOi8vd3d3LnczLm9yZy9UUi94aHRtbDEvRFREL3hodG1sMS1zdHJpY3QuZHRkIj4KCjxo dG1sIHhtbG5zPSJodHRwOi8vd3d3LnczLm9yZy8xOTk5L3hodG1sIj4KCjxoZWFkPgoKPHN0eWxl IHR5cGU9InRleHQvY3NzIiBtZWRpYT0iYWxsIj4KdWwjdG9wbWVudSB7CiAgICBtYXJnaW46IDA7 IAogICAgcGFkZGluZzogMDsgCiAgICB3aWR0aDogMTUwcHg7IAogICAgcG9zaXRpb246IGZpeGVk OyAKICAgIHRvcDogMHB4OyAKICAgIGxlZnQ6IDBweDsgCiAgICBiYWNrZ3JvdW5kLWNvbG9yOiB3 aGl0ZTsKfQp1bCN0b3BtZW51IGxpIHsKICAgIHBvc2l0aW9uOiByZWxhdGl2ZTsgCiAgICBsaXN0 LXN0eWxlOiBub25lOyAKICAgIG1hcmdpbjogMHB4OwogICAgcGFkZGluZzogM3B4OwogICAgYm9y ZGVyLWJvdHRvbTogMXB4IHNvbGlkICM4ODg7Cn0KdWwjdG9wbWVudSB1bCB7CiAgICBiYWNrZ3Jv dW5kLWNvbG9yOiB3aGl0ZTsgCiAgICB6LWluZGV4OjEwMDsKICAgIHdpZHRoOjE0MHB4OyAKICAg IGRpc3BsYXk6IG5vbmU7CiAgICBtYXJnaW46IDBweDsKICAgIHBhZGRpbmc6IDBweDsKICAgIHBv c2l0aW9uOiBhYnNvbHV0ZTsgCiAgICB0b3A6IC01cHg7IAogICAgbGVmdDogOTYlOwoKfQp1bCN0 b3BtZW51IGxpOmhvdmVyID4gdWwgewogICAgZGlzcGxheTogYmxvY2s7IAp9Cjwvc3R5bGU+Cgog CjwvaGVhZD4KCgo8Ym9keSBvbmxvYWQ9Ik9uTG9hZCgpIj4KPHVsIGlkPSJ0b3BtZW51Ij4KPGxp IGNsYXNzPSJzdWIiPk1lbnUgSXRlbQo8dWw+CjxsaT48YSBocmVmPSJ0ZXN0MS5odG1sIj5TdWIt SXRlbSAxPC9hPjwvbGk+CjxsaT48YSBocmVmPSJ0ZXN0Mi5odG1sIj5TdWItSXRlbSAyPC9hPjwv bGk+CjxsaT48YSBocmVmPSJ0ZXN0My5odG1sIj5TdWItSXRlbSAzPC9hPjwvbGk+CjxsaT48YSBo cmVmPSJ0ZXN0NC5odG1sIj5TdWItSXRlbSA0PC9hPjwvbGk+CjwvdWw+CjwvbGk+CjwvdWw+CgoJ PHNwYW4gInN0eWxlPSJmb250LXNpemU6ODBweCI+dGVzdCB0ZXh0IGhlcmUuICB0ZXN0IHRleHQg aGVyZS4gIHRlc3QgdGV4dCBoZXJlLiAgdGVzdCB0ZXh0IGhlcmUuICB0ZXN0IHRleHQgaGVyZS4g IHRlc3QgdGV4dCBoZXJlLiAgdGVzdCB0ZXh0IGhlcmUuICB0ZXN0IHRleHQgaGVyZS4gIHRlc3Qg dGV4dCBoZXJlLiAgdGVzdCB0ZXh0IGhlcmUuICB0ZXN0IHRleHQgaGVyZS4gIHRlc3QgdGV4dCBo ZXJlLiAgdGVzdCB0ZXh0IGhlcmUuICB0ZXN0IHRleHQgaGVyZS4gIHRlc3QgdGV4dCBoZXJlLiAg dGVzdCB0ZXh0IGhlcmUuICB0ZXN0IHRleHQgaGVyZS4gIHRlc3QgdGV4dCBoZXJlLiAgdGVzdCB0 ZXh0IGhlcmUuICB0ZXN0IHRleHQgaGVyZS4gIHRlc3QgdGV4dCBoZXJlLiAgdGVzdCB0ZXh0IGhl cmUuICB0ZXN0IHRleHQgaGVyZS4gIHRlc3QgdGV4dCBoZXJlLiAgdGVzdCB0ZXh0IGhlcmUuICB0 ZXN0IHRleHQgaGVyZS4gIHRlc3QgdGV4dCBoZXJlLiAgdGVzdCB0ZXh0IGhlcmUuCjwvc3Bhbj4g CgoKCgo8L2JvZHk+CjwvaHRtbD4K
