Recent Questions Javascript Tree Menu
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 Javascript/DHTML Tree such as in JavaScript Tree 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.
Javascript/DHTML Tree works fast, but 10000 is a large value. Please, try atrial version of Javascript/DHTML 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 Javascript/DHTML Tree into the <table> or <div>.
Q: How do I make the submenus sticky i.e. they will not close even when the mouse goes to somewhere else on the page?
A: I've checked your menu in all browsers. I can't see such problem.
You can try to adjust these parameters:
var transDuration=200; // Delay of a transitional effect (in ms) on submenu's showing.
var transDuration2=100; // Delay of a transitional effect (in ms) on submenu's hiding.
Q: I am using your javascript menu over. I have had a report today that the menu is problematic with IE8. As follows:
"A bit more of a concern is in IE8 where the menu does not function correctly in general at all. When you hover over the menu text the sub menu appears, but when you move your mouse across to select an item off the sub menu it closes. "
Are you able to confirm and rectify his problem?
A: Yes, our menu has some problems with IE8, because IE8 is a betaversion and has just a part of future functionality, for exampleit still doesn't have filters.
We're planning to add the full support for IE8as well as for all major browsers.
All issues will be fixed with final version of IE8.
Q: I'd like to purchase your deluxe menu, but for the life of me I cannot figure out how to align the javascript sub menu to the top of the primary menu in Firefox. It aligns correctly in IE but in Firefox it is dropping by 20 pixels or so below where I want it.
A: This is space to document borders. We've set this space, so that yourjavascript sub menu will not look like the part of browser window. If you wantyou can delete that space.
Open dmenu.js file in any text editor and find the following code:
space=15;
Change 15 to 0.
space=0;
