Recent Questions Dropdown Tree Menu Yui
Q: I got the menu to display across frames, but it displays differently in Firefox & Mozillavs. Internet Explorer. Is that to be expected?
In The Mozilla-based browsers, the submenu butts right upunder the main menu – which is how I want it. In IE, it is about 10 pixels below.
Also, I can’t get the submenus to drop down directly under the main menus – they are offset by about 100 pixels to the right.
A: The problem is in a structure of your frameset.
Mozilla browsers can't determine absolute coordinates for a frame, sosubmenus drop down with an offset.
You should create the following frameset structure:
--|------------
| menu
--|------------
|
| submenus
|
Now a top row has 2 columns and all browsers can determine awidth of the 1st column in the second row.
Q: I haven’t had any problems using the drop line menu, until now when I had to make some changes. After adding some sub-menu items on two of the drop line menu buttons, those menu’s drop down upwards, instead of downwards like the rest. I tried deleting them and remaking them, but then the menu appeared to have no image behind it, only a colour. So I duplicated a working menu item, and then modified it to be what I wanted – and it still drop down upwards!
A: Please check the following drop line menu parameter:
var subMenuVAlign="top";
Q: I was wondering why when I add the code below the flash disappears in safari, but now works in Firefox, when the dropdown menu is rolled over? Can it work in both Safari and Firefox?
function dm_ext_ruleObjectHide()
{
// Safari detect
if ((parseInt(navigator.productSub)>=20020000) && (navigator.vendor.indexOf('Apple Computer') != -1) && (navigator.product=='Gecko'))
return true;
else
return false;
}
A: The following code in this function
// Safari detect
if ((parseInt(navigator.productSub)>=20020000) && (navigator.vendor.indexOf('Apple Computer') != -1) && (navigator.product=='Gecko'))
return true;
hides flash in Safari.
JavaScript Tree Menu can't drop down over an object correctly in Safari that iswhy the latter will be hidden for a time when the submenu is shown.
You can try to delete this code.
Q: Cross-frame mode: after clicking on a menu item and the subframe is loading and then mouse over the menu when the subframe has not finished loading a javascript error occurs and then the javascript vertical menu breaks.
A: You can get this error when you load pages from the another domain.
JavaScript Tree Menu can support this mode for the same domain only -- ifyou loaded a page to a subframe from another domain, the submenuscan't be shown in it. It happens because all browsers don't allow todo that for security reasons. Just imagine if you'll able to create aframeset from 2 frames, 1st frame will be with a zero height-width,and you'll load your page into it. Then user will go to another domainand your "invisible" frame will change a content of other pages!
