Q: I just noticed as well that I cannot change the spacing of the buttons.
Right now the buttons are tight together, how do I create a gap between each dhtmlmenu button?
A: You can paste the separator.
Please, see the following parameters:
//------- Separators -------
var separatorWidth = "10";
var separatorHeight = "20";
var separatorAlignment = "center";
var separatorImage = "C";
var separatorVWidth = "150";
var separatorVHeight = "10%";
var separatorVImage = "image.jpg";
You can create separators using menuItems, for example:
var menuItems = [
["item 1"],
["-"], // this item is separator
["item 2"],
];
You can also use this parameter:
var itemPadding = "4px";
You can also set multiple values, for example:
"2px 15px 5px 5px";
(top, right, bottom, left)
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: It's been couple of months since I last time asked something about tree menu. I am still evaluating the software.
I have a short question. Is it possible to use CSS instead of JavaScript to tune the look and feel of the tree menu? For example I would be interested in giving menu css java item height value in relative numbers (em or %) rather than specifying a size in pixels...
A: But actually you can use 'em' and '%' units in Deluxe Tree, forexample.
var tmenuWidth="13em";
var tmenuHeight="12em";
var tmenuWidth="35%";
var tmenuHeight="15em";
Q: How can I center my navigation java script menu bar within my HTML page? I have tried putting the script into a table that is centered. I have also changed the var menuWidth to 800px. The navigation bar is still right-justified instead of centered in both IE and Firefox/Mozilla.
A: Now you use absolute position for the java script menu bar:
var absolutePos=1;
var posX="0px";
var posY="0px";
You should set:
var absolutePos=0;
