Recent Questions Sites Using 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 customizable is it style in for dhtml navigation, meaning, i have images i want used for the top level navigation, and background images for the rest. any way I can achieve this?
A: Actually you can create any menu with JavaScript Tree Menu. You can use Individual Styles tocreate your menu.
For example:
var itemStyles = [
["itemWidth=92px","itemHeight=21px","itemBorderWidth=0","fontStyle=normal 11px Tahoma",
"fontColor=#FFFFFF,#FFFFFF","itemBackImage=data-vista-03.files/btn_magentablack.gif,data-vista-03.files/btn_magenta.gif"],
];
var menuStyles = [
["menuBackColor=transparent","menuBackImage=back.gif","menuBorderWidth=0","itemSpacing=1","itemPadding=0px 5px 0px 5px"],
];
Q: Is it possible to create expandable checkbox menu with you javascript dynamic tree menu?
(I want each tree menu element contain a check box and some text. )
A: No, unfortunately Javascript/DHTML Tree doesn't have such a feature now.
But you can paste any html code inside item text, for example:
["+Support", "", "icon5_t.gif", "icon5_to.gif", "", "Support Tip"],
["|Index <select style='width:120px;height:17px;font:normal 10px Tahoma,Arial;'><option>Section 1<option>Section 2<option>Section 3</select>","", "", "", "", "","", "0"],
["|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"],
["|Write Us", "", ""],
["|<INPUT TYPE=checkbox CHECKED ID=chk1 onclick='choosebox1()'>Uncheck this check box for some free advice","","","",],
["<img src='img/sep.gif' width=113 height=1>"],
Q: When I put any new link on my tree view expand it goes as if I am placing as _blank when I have it leading to _self.
A: At the moment you have:
var titemTarget="_blank";
And you haven't specified "_self" parameter to
["||Unilock Fireplace MODS","fireplace_unilock_mods.htm", "", "", "", "", "", "", "", ],
You should set
var titemTarget="_self";
or set "_self" parameter for each item individually:
["||Unilock Fireplace MODS","fireplace_unilock_mods.htm","", "", "", "_self", "", "", "", ],
