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: Please tell me where I am going wrong:
The menu is all messed up!
A: See, now you have:
var itemBackImage=["data.files/btn_green.gif","data.files/btn_whitegreen.gif"];
and you also assign Individual Item Style with itemBackImage anditemWidth parameters for each item
var itemStyles = [
["itemWidth=92px","itemBorderWidth=0","fontStyle=normal 11px Tahoma","fontColor=#000000,#000000",
"itemBackImage=data.files/btn_whitegreen.gif,data.files/btn_white_white.gif"],
];
var menuItems = [
["projects","", , , , , "0", "0", , ],
["FMWR","", , , , , "0", "0", , ],
["general water info","", , , , , "0", "0", , ],
["bulletin board","", , , , , "0", "0", , ],
["WSS MDG tracking","", , , , , "0", "0", , ],
["reform instruments","", , , , , "0", "0", , ],
You should delete itemBackImage and itemWidth parameters from itemStyles.
Q: I've been working with your javascript menu sample and like what I see so far. One issue I have seems to be with the smColumns variable. I'm assuming it was for just the sub menus but in the trial when I change this the entire menu goes into multi- column mode. I exported the project to HTML thinking I could manually change it there, that produced the same result, changed the entire menu to multi-column.
Our menu will be dynamic (populated from SQL Server) with only some of the sub menus being multi-column. We will even have multiple sub menus for certain items and we'll need to have the capability to set which one of those will be displayed in Multi-columns and which ones will not. (See Below) So the question becomes; Is there a way to set the number of columns only for the javascript menu sample subitems we desire to have multi-column and if so how?
A: You should use Individual Styles and set number of javascript menu sample submenu columns foreach submenu individually.
var menuStyles = [
["smColumns=2","smOrientation=undefined"],
];
Q: Tree menu doesn't display properly in Firefox or IE7. Could you give me advice on how to correct this problem? The menu creates black 'blinds' horizontally across the page. Since IE7 will be rolling out soon I need to get this corrected sometime in the next couple weeks.
A: Try to specify units in "px".
var tmenuWidth = "280px";
It's necessary to specify exact value for Mozilla browsers. It helps to position menus correctly.
