Q: We are using a licenced version of your tree-menu.
Now we have a situation, where we should show the actualclicked menu position with an icon or a color for a collapse tree menu.
A: This can be found with the help of external function of tree menu.
dtreet_ext_userClick(itID, event) - this function is called when clicking a mouse button on the item.
itID - item id
event - standard structure of events generated browser
dtreet_ext_getItemParams (menuInd, itemID) - returns all item parameters.
Please visit http://deluxe-tree.com/functions-info.html for addition information.Q: I am in the final stages of testing and need some advice and help.
I have two problems I am trying to address.
1) Arrows on dropdown menu select.
2) Load time.
Please notice, I have to use absolute paths for the dropdown menu select to work.
1) I can't get the arrows to show, so I tried to add the code for images in the first bold sentence below.
2) I tried to add the second line for absolute paths for links to increase load time in the second bold sentence. It appears that the load time is increased by about 3 seconds and that the menu is the last to load, even though I have tried to have this as the first html to load.
Neither one of my commands appear to work.
This site has over 10,000,000 items on it, and I can't wait to get this up and running. Your program is the perfect solution for anybody with a website.
A: 1) Now you have:
var arrowImageMain=["mainmenu.files/arrv_blue_2.gif","mainmenu.files/arrv_white_2.gif"];
var arrowImageSub=["mainmenu.files/arr_blue_2.gif","mainmenu.files/arr_white_2.gif"];
You should set your arrows in the following way:
var arrowImageMain=["arrv_blue_2.gif","arrv_white_2.gif"];
var arrowImageSub=["arr_blue_2.gif","arr_white_2.gif"];
2) Your menu is very large. I advise you to us AJAX like technology.

You can also try the following things:
move all <script> calls into <head>, but delete dm_init() function from mainmenu.js file -- move them instead offiles calls, i.e.:
<head>
<script src=mainmenu.js>
...
</head>
...
<div><script>dm_init();</script></div>
It this case data will be loaded when <head> will load, but after thatdropdown menu select must be shown quickly.
Let me know about results.
Q: Is there a way to have the menu stay expanded in the same exact state when
I click on a menu item of the javascript tree view and go to a new page?
A: There is no need to write additional code on a server side to remember what items were expanded/collapsed.
DHTML Tree Menu can save items state automatically.
Please, see the example of the menu that works with cookies:
http://dhtml-menu.com/tree-examples/tree-menuxp-save-state.html
Set the following parameter:
var tsaveState = 1;
and the menu remembers its structure for each user who visit your page.
Try to expand/collapse items. Then reload the page and you'll see results.
Q: Is there any way to keep a menu lit up when going to another page? Or do the menus always have to default back to their normal state?
I want the menu to know what page the user is on and keep that section highlighted. Any ideas?
A: You should set a pressed item using Javascript API:
function dm_ext_setPressedItem (menuInd, submenuInd, itemInd, recursion)
Sets a current pressed item.
menuInd - index of a menu on a page, >= 0.
submenuInd - index of a submenu, >= 0.
itemInd - index of an item, >=0.
recursion = true/false - highlight parent items.
But notice, to use dm_ext_setPressedItem() you should know ID of selected item and subitem.
You can't get this ID after you reload your page. That is why you should write your own code on PHP.
