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: One more question. How can I make the javascript submenus appear much more quickly? They appear but only after mouseing-over the menu and waiting for approximatelyone second.
A: Try to adjust the following parameters:
var dm_writeAll=0;
var smShowPause=100;
var smHidePause=1000;
var transDuration=150;
var transDuration2=200;
You can also turn off transitional effects
var transition=-1;
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: Thnx, it works now, just one more question :-)
I use frames on my website, the target frame name is main.
But when i put main as target in the simple javascript drop down menu, it loads as a new windows, do you know what i'm doing wrong?
A: You can set target parameter for all items:
var itemTarget="main";
Where main - is the name of the frame where you want to open the link.
or for each item individually:
["Home","testlink.html", "", "", "", "main", "", "", "", "", "", ],
