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 Deluxe Tree such as in Deluxe 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.
Deluxe Tree works fast, but 10000 is a large value. Please, try atrial version of Deluxe 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 Deluxe Tree into the <table> or <div>.
Q: I was wondering why when I add the code below the flash disappears in safari, but now works in Firefox, when the dropdown menu is rolled over? Can it work in both Safari and Firefox?
function dm_ext_ruleObjectHide()
{
// Safari detect
if ((parseInt(navigator.productSub)>=20020000) && (navigator.vendor.indexOf('Apple Computer') != -1) && (navigator.product=='Gecko'))
return true;
else
return false;
}
A: The following code in this function
// Safari detect
if ((parseInt(navigator.productSub)>=20020000) && (navigator.vendor.indexOf('Apple Computer') != -1) && (navigator.product=='Gecko'))
return true;
hides flash in Safari.
Deluxe Menu can't drop down over an object correctly in Safari that iswhy the latter will be hidden for a time when the submenu is shown.
You can try to delete this code.
Q: I'm trying to display the submenus to the left of the menu. I searched your questions and found one that said to use the following:
var smViewType=2;
I added this but it didn't do anything.
A: Try to use this parameter:
var subMenuAlign = "left";
Q: We are unable to get sub-menus to appear on page load or rather simulate a "windows application style menu".
How can we in combination with the java menu api function dm_ext_setPressedItem get the associated sub-menu to display? This function simply sets the item to "pressed" rather than actually showing the sub-menu. Attempts at beginning an item's text value with "+" only works with Deluxe Tree.
Again, we are trying to use the menu not only as a navigator but also as a visual aid for the user to determine what page they are viewing. For example, when a user clicks on a menu item and that page loads, the menu should display the top-level item pressed, the sub-menu group, and the item pressed.
Furthermore, it would also be useful if we could then "unlock" the pressed items and navigate the menu under normal circumstances.
If there are no existing "quick" functions to accomplish this, could you please point out the function in dmenu.js or another engine file that initiates the display of sub-menus, we could then force the menu to select a top-level item in the onload event thus showing a top-level item pressed along with it's related sub-menu.
A: Unfortunately Deluxe Menu doesn't have such a feature now. It is notpossible to set parent item highlighted, expanded submenu group andhighlighted submenu item.
You can do it using Deluxe Tree now only.
