Q: Hello. I have noticed that when you expand a menu and then click to another page, the menu is collapsed on the next page. I read about "state saving" and tried the parameter which did not work. Is there a way to accomplish this?
A: You can see the example for state saving here:
http://dhtml-menu.com/tree-examples/tree-menuxp-save-state.html
This menu saves its state.
To enable this mode you should include dtree_ss.js file intoyour html page and set the following parameter:
var tsaveState = 1;
See, if you open pages (with menus) from different folder itmeans that you open different menus. So, when you change a state, forexample, of the first menu within "content/" folder and then openanother page with the menu within "content/subfolder/", browsers looks for anothercookie file and can't find it and the second menu stays in a defaultstate. Is it clear?
Q: I am having some difficulty dynamically adding items to a tree javascript and menu.
I have a menu with one "root" item. I see the use of the "+" symbol within the item name. I do not see any documentation regarding this symbol, only "|". Can you explain?
If I have one menu with this one "root" node, how would I add an subitem to this root node?
Here is my code so far, but the inserted items appear to be at the same level as the root node.
var rootItem = dtreet_ext_getItemIDByIndex ( 0,0 );
var menuItem = new Array(10);
for ( var i = 0; i < producers.length; i++ )
{
var producer = producers[ i ];
menuItem[0] = producer.name;
dtreet_ext_insertItem ( 0, 0, i + 1, menuItem );
A: See dtreet_ext_insertItem () function has the following parameters:
function dtreet_ext_insertItem (menuInd, parentItemID, itemInd, itemParams)
Creates a new item and inserts it into a specified position.
menuInd - index of a javascript and menu on a page, >= 0.
parentItemID - ID property of an item.<, >= 0.
itemInd - index of a new item within the javascript and menu, >= 0.
itemParams - item parameters.
Notice that parentItemID is the Id property of the parent item (notindex). If you want to add top items you should set parentItemID=0.
itemInd - you should use this parameter if you want to add item in thespecific place, for example set itemInd=5 if you want to add itembefore the existing item with itemInd=5.
If you set itemInd=null the new item will be added at the end of this submenu and its index will be added automatically.
Q: How do you labeling the various segments of your page to utilize the horizontal menu tabs?
A: See, for each item you should assign the ID property of the contentDIV (see data file with your menu parameters).
["Style Name","contentName", "", "", "", "", "1", "", "", ],
["-","", "", "", "", "", "0", "", "", ],
["Style Description","contentDescription", "", "", "", "", "", "", "", ],
["-","", "", "", "", "", "0", "", "", ],
["Style Variations","contentVariations", "", "", "", "", "", "", "", ],
["-","", "", "", "", "", "0", "", "", ],
["Empty","", "", "", "", "", "2", "", "", ],
And on your html page you should create DIV's with such ID.
<div id="contentName" style="height: 0%; visibility: hidden;" class="tabPage">
<br><br><br>
<p align=center><img src="img/style01_title.gif" width=140 height=90 alt="Glass Style Tabs"></p>
<br><br><br>
You should paste your content here!!!!!
</div>
<div id="contentDescription" style="height: 0%; visibility: hidden;" class="tabPage">
<br><br><br>
<p align=center><img src="img/style01_title.gif" width=140 height=90 alt="Glass Style Tabs"></p>
<br><br><br>
You should paste your description here!!!!!
</div>
You can paste any code within DIV's (PHP, Javascript ...)
Q: I have small problems with your javascript menu system.
#1. I am creating a multi-level menu, am I limited to a gird format or can every item have a variable column width?
#2. With submenus, I want to have the submenu be the same width as the parent cell, is there a simple command for this, or do I have to guess the column widths until it fits correctly?
#3. In those same submenus, I have items that are longer than the parent, is there a word wrap or a way to define a break, rather than having the scroll feature?
A: 1) You should use Individual Item Styles.
For example:
var itemStyles = [
["itemWidth=120","itemBorderWidth=1","itemBorderStyle=solid,solid","itemBackColor=#ACF88B,#ACF88B","itemBorderColor=#329309,#329309"], //style0
["itemWidth=100","itemBorderWidth=1","itemBorderStyle=solid,solid","itemBackColor=#FFFFFF,#FFFFFF","itemBorderColor=#1B92E9,#1B92E9"], //style1
["itemWidth=130","itemBorderWidth=1","itemBorderStyle=solid,solid","itemBackColor=#FF9684,#FF9684","itemBorderColor=#EC7575,#EC7575"], //style2
["itemWidth=150","itemBorderWidth=1","itemBorderStyle=solid,solid","itemBackColor=#84F9FF,#84F9FF","itemBorderColor=#00B8C1,#00B8C1"], //style3
];
var menuStyles = [
["smColumns=2"], //style0
];
["Home","testlink.htm"],
["Samples","testlink.htm"],
["|Group 1","", , , , , "0", , , ],
["|Group 2","", , , , , "1", , , ],
["|Group 3","", , , , , "2", , , ],
...
[" More Samples","testlink.htm"],
["|Group 1","", , , , , "3", "0", , ],
["|Group 2","", , , , , "1", , , ],
Where "0", "1", "2", "3" - style number in itemStyles.
2) You can also use Individual Item Styles.
var itemStyles = [
["itemWidth=120px"],
];
var menuStyles = [
["smWidth=120px"],
];
["Product Info","", "default.files/icon1.gif", "default.files/icon1o.gif", , , "0", , , ], // itemStyles
["|Features","testlink.html", "default.files/icon2.gif", "default.files/icon2o.gif", , , , "0", , ],
["|Installation","", "default.files/icon2.gif", "default.files/icon2o.gif", , , , , , ], // menuStyles
3) Try to set this parameter:
var noWrap=0;
