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: Am I under the correct assumption that if the inner menu item text expands past the ItemWidth or MenuWidth (being that the Width is set -- eg 150px), that the javascript menu div width will expand past it's boundaries instead of wrapping the text? (eg. A text like "Please Make this Wrap instead of expand the width boundary" seems to expand the container's width rather than wrap)
A: There are 2 ways to do that:
1. set
var noWrap=0;
2. use <br> tags, for example:
var menuItems = [
["line 1<br>line 2"],
];
Q: I’d like to know how to populate the navigation bar menu from a database?
A: Please, see the example of .php file.The content of .php file depends on your database structure.
<?php
// The example for PHP/MySQL.
// MySQL database has the table "menuTable" that contains data for menu items.
// The table has the following fields:
// 1. "text" - item text
// 2. "link" - item link
// 3. "icon1" - item icon (normal state)
// 4. "icon2" - item icon (mouseover state)
function getMenuItems()
{
$jsItems = '';
// Select all records from table "menuTable"
$allItems = mysql_query('SELECT * FROM menuTable;');
// Extract items data from database and build Javascript code for menuItems
while ($itemData=mysql_fetch_array($allItems))
{
$jsItems .= '["'.$itemData['text'].'", "'.$itemData['link'].'", "'.$itemData['icon1'].'", "'.$itemData['icon2'].'"],';
}
// Return Javascript code
return $jsItems;
}
?>
<script>
var menuParam1 = value1;
var menuParam2 = value2;
var menuParam2 = value2;
...
var menuItems = [
// Write Javascript code for menu items
echo getMenuItems();
?>
];
</script> Q: Does your menu system support imbedded check boxes? I want to be able to use menus to help users select options and want to have those selections УstickФ for the duration of their session. Do you have any examples of this?
A: Yes, you can insert any html code within menuItems, for example:
["|You can place <b>any HTML code</b><br> to item, for example <u>image</u>:<br><img src=img/logo.gif>","testlink.html"],
["|Index <select style='width:120px;height:17px;font:normal 10px Tahoma,Arial;'><option>Section 1<option>Section 2<option>Section 3</select>", "", "", "", "", "", "", ""],
["|Search <input type=text style='width:80px;height:17px;font:normal 10px Tahoma,Arial;'> <input type=button value='Go' style='width:30px;height:17px;font:normal 10px Tahoma,Arial;'>", "", "", "", "", "", "", "0"],
