Q: Hi, I need to know if it is possible to accomplish the following functionalities with your tree-menu library.
1. I need to have two or more trees in the same page
2. I need to have a checkBox in each node and through a JavaScript function be able to add the selected nodes into another tree.
3. I need to eliminate the nodes that has check=true
4. I need to populate on-demand the tree using AJAX
5. I need to implement drag&drop through the use of the mouse events on the tree nodes
6. How would the tree behave with 10000 nodes??
7. I need to have a tree within another element that uses scroll
such as a DIV or SPAN (fixed area). When collapsed or expanded, the area should remain its original size.
A: 1. You can add any number of the menus on the one page.
2, 3, 5. Yes, you can do it. But you should create your own server-side script (for example, php) that will do it. The menu doesn't support such a feature.
4. Unfortunately, you can't use the AJAX-like technology in the Deluxe Tree such as in Deluxe Menu.
6. It is possible that the loading speed can be lower if the menu is very large. But it doesn't take so much time.
Yes, you can notice some delay in IE, but in over browsers it works better.
Deluxe Tree works fast, but 10000 is a large value. Please, try atrial version of Deluxe Tree.
I tried to create large menus on my machine: P4 3GHz, 512RAM WinXP SP2
It takes:
- 1000 items ~ 10 sec
- 2000 items ~ 40 sec
7. You can paste Deluxe Tree into the <table> or <div>.
Q: I was using the trial version with no problems. However, once I upgraded to the full version as above, I am having problems getting my DHTML menus to work properly. I'm using xp pro with ie7. As I said before, I had no problems with the trial version.
Whenever I click on a menu java tab now, ie7 displays an error message in the corner. When clicked it reads:
Line: 18
Char: 16940
Error: 'tabs[...]id' is null or not an object
Code: 0
I am using the 'Microsoft Like Style' tabs template in your DHTML tuner software. I get no errors when the tabs are not linked to hidden <div> tags. However, when they are linked to display the hidden <div> tags I get the error. But they do still display the correct hidden <div> tags after 2 or 3 clicks.
A: Try to set the following menu java parameter:
var bselectedSmItem=0;
Q: There is a default gap between two collapsible javascript menu buttons. Suppose the two menu are "Company profile" and "Service", there is a default gap between those tow , it is not taking the specified space( for example I am putting 2px gap but it is taking a default gap) Please suggest me the solution for the same.
A: You should use new parameter in the data file:
var tXPMenuSpace=0;
Q: I have implemented a deluxe-menu on my client's website and I had a couple of questions.
1. Can I control how fast the submenus scroll in my javascript menu examples? If you look at the site and hover over Need An Expert? on the menu and then point to Practice Areas, this submenu seems to scroll slower than if you mouse over "Technology" and scroll that submenu. The Technology submenu scrolls a lot faster. Is it because there are many more items in the Technology submenu? I tried to find a setting for "scroll speed" or the like, but I couldn't find it.
2. In internet explorer, when you mouse over Need An Expert?, Technology the first time you go to the page, there is a 3-4 second delay before the submenu opens. There are a lot of submenu items under Technology, but in Firefox, there doesn't seem to be this delay. Do you know why this would happen in IE? Is there a way to fix it? Could the problem be that each submenu item has a background graphic and this is causing the delay?
3. When you get to a page on the site and you rollover the top level menu, there is also a delay before the background image of the menu items shows up. You get a solid blue background color for a second or two (the bgcolor assigned) and then the graphic loads and shows up. Is there any way around this? I have a javascript to preload the image (back.jpg) but that doesn't seem to help.
Any help would be greatly appreciated!!!
A: 1. The scroll speed depends on number of items to be scrolled, more items -> faster scroll.
You can decrease the number of items or enlarge the size of submenu.
2,3. Please try to add the following param:
var dm_writeAll = 1;
It will load all backgrounds on page load, no on mouseover.
