View Full Version : Menu opening in the wrong direction

10-11-2010, 09:33 AM
1) Script Title: Flex Level Drop Down Menu (v1.1)

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex1/flexdropdown.htm

3) Describe problem: I have the Menu on a Website on the upper side of the screen and most of the times it pops up normally, but sometimes it opens above the menu bar, "behind" the address-bar of the browser and out of the screen. This even happens when there are just 4 Menu entries and enough space under the menu bar.

How can i set the Menu system to just open under the menu bar?

To disable the menus from ever dropping up (so it always just drops down), inside the .js file, try locating function positionul(), and comment out the following two lines (added code in red):

positionul:function($, $ul, e, $anchor){
var istoplevel=$ul.hasClass('jqflexmenu') //Bool indicating whether $ul is top level flex menu DIV
var docrightedge=$(document).scrollLeft()+$(window).width()-40 //40 is to account for shadows in FF
var docbottomedge=$(document).scrollTop()+$(window).height()-40
if (istoplevel){ //if main flex menu DIV
var offsets=$anchor.offset()
var anchorsetting=$anchor.data('setting')
var x=offsets.left+anchorsetting.useroffsets[0]+(anchorsetting.dir=="h"? $anchor.outerWidth() : 0) //x pos of main flex menu UL
var y=offsets.top+anchorsetting.useroffsets[1]+(anchorsetting.dir=="h"? 0 : $anchor.outerHeight())
x=(x+$ul.data('dimensions').w > docrightedge)? x-(anchorsetting.useroffsets[0]*2)-$ul.data('dimensions').w+$anchor.outerWidth()+(anchorsetting.dir=="h"? -($anchor.outerWidth()*2) : 0) : x //if not enough horizontal room to the ridge of the cursor
//y=(y+$ul.data('dimensions').h > docbottomedge)? y-(anchorsetting.useroffsets[1]*2)-$ul.data('dimensions').h-$anchor.outerHeight()+(anchorsetting.dir=="h"? ($anchor.outerHeight()*2) : 0) : y
else{ //if sub level flex menu UL
var $parentli=$ul.data('$parentliref')
var parentlioffset=$parentli.offset()
var x=$ul.data('dimensions').parentliw //x pos of sub UL
var y=0
x=(parentlioffset.left+x+$ul.data('dimensions').w > docrightedge)? x-$ul.data('dimensions').parentliw-$ul.data('dimensions').w : x //if not enough horizontal room to the ridge parent LI
//y=(parentlioffset.top+$ul.data('dimensions').h > docbottomedge)? y-$ul.data('dimensions').h+$ul.data('dimensions').parentlih : y
$ul.css({left:x, top:y})
