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: We are using the deluxe menu in one of our projects. The menu works well on our integration system but not on our production system.
The only difference is that the integration is running on Tomcat Version 5.5.9 and the production (with the "broken" menu) on Tomcat 5.5.17.
But for me it looks more like a browser problem than a JSP problem.
Unfortunatley the Tomcat 5.5.17 is our production system so fast help is appreciated.
A: Try to set the following parameter:
var dmObjectsCheck=1;
Make sure that you have dmenu_add.js file in the same folder withdmenu.js file.
Q: I have another question:
Menu behavior in SAFARI is does not properly work compared to EXPLORER.
If you have a look at the site via SAFARI, please do the following:
Example:
Under menu "Projets" select "par pays" then "Afrique" then "Algerie".
It will then show a left hand menu. Please select "2008/2010".
It will correctly show content.
Then if you try to select again via menu "Projets"; the html menu navigation does not show anymore the submenus. You still need to click a menu without submenus, like "News", and then afterwards you can click "Projets" and the system will again show submenus.
This strange behaviour does not appear in EXPLORER nor in FIREFOX.
A: The problem is in your frame structure after you open "Projets" select "par pays" then "Afrique" then "Algerie".
Your menu won't work correctly with such frame structure.
You should use the following frame structure for all pages at once:
--------------------------------------------------------
topFrame with the html menu navigation
--------------------------------------------------------
Algerie_leftFrame |
with | Algerie_mainFrame
Tree Menu |
--------------------------------------------------------
bottomFrame
--------------------------------------------------------
and write your init function in the following way:
dm_initFrame("frmSet", 0, 2, 0);
Or you shouldn't use Algerie_leftFrame and Algerie_mainFrame at all (use one mainFrame) and write your init function in the following way:
dm_initFrame("frmSet", 0, 1, 0);
Q: Can I show / hide the javascript floating menu as needed.
A: You should paste javascript code into item's link field of the floating menu,for example:
var menuItems =
[ ["text", "javascript:document.getElementById('dm0m0').style.visibility='hidden'", ...]
];
