Recent Questions Javascript Treeview Disable Autopostback Select Node
Q: As a part-time webdeveloper I have gotten very interested in your product. I really appreciate a number of things
- it's very flexible
- it's very easy to work with
- examples nicely show the capabilities
But I have a couple of questions:
- When opening a menu, there is an option for keeping the menu-item that has been pressed hightlighed (so that the user can see what he/she pressed). Is it possible, programmatically, to decide when this highlighting should be removed? The scenario is that, when a menu-item is clicked the used might browse for a couple of pages within the context defined by the menu-item, but when the user leaves, the menu-item should no longer be highlighted. I will (programmatically) decide the context, but is it possible for me to interact with the menu, and for example decide explicitly which menu should be highlighted?
- Our design department would like the menu containing the elements: "Skovdrift, Juletreer, Skovrejsning, etc". Please notice that "Brende" is supposed to show a menu item that is hightlighted. Is is possible to create this menu such that it is dynamic and each item is text-based (and not based on two pictures for each menu-entry: hightlighted and not)? I've been wondering how to solve this problem, but I cannot figure out a solution. The problem that I is stuck at, is how organise this speciel "frame" around each menu-element. Something that be partly accomplished using "arrowImageMain", but that does not bring me all the way. Please notice that the menu-items might not have any sub-menu.
A: I suppose that you're saying about
var pressedItem=-2;
Defines an item that will appear in the highlighted state
(-2 - normal mode, -1 - toggle mode is active, but highlighted item not defined, 0,1,2,3,... - # of pressed item including separators)
This parameter will not approach you.
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.
Q: How do I turn off the transitional effects for the html menus (is there a flag)?
A: To turn off transitional effects you should set the following parameters:
var transition=-1;
var transOptions="";
var transDuration=0;
var transDuration2=0;
Q: The cascading javascript menu does not spans frames or windows like Applets. Is that correct?
I was not able to make the sample to do it.
A: The DHTML Menu and Java Menu are built on different technologies.Java menus can create submenus that cover frames as a standard Windowssubmenus. DHTML Menu can't do that, because it's controls is htmlobjects, they can't overlap Windows controls. So, cascading javascript menu hascross-frame ability that allows it to show submenus in differentframes. But it can support this mode for the same domain only -- ifyou loaded a page to a subframe from another domain, the submenuscan't be shown in it. It happens because all browsers don't allow todo that for security reasons. Just imagine if you'll able to create aframeset from 2 frames, 1st frame will be with a zero height-width,and you'll load your page into it. Then user will go to another domainand your "invisible" frame will change a content of other pages!

Q: I would like, that not only the text is represented differently when dhtml nav menu item is expanded, also the Icon separates before it at the side where I am.
iconarrs.gif is not right
iconarrs_aktiv.gif is right
How do I solve that?
A: You should set arrow for expanded state
