Recent Questions Javascript Tree Sample
Q: I'm struggling with one last issue on my navigation. When you have a screen resolution about the same size as the site width, when a sub menu pops up, It displays sometimes to the left of the first drop down menu list rather than the left. Is there a way of changing the way this displays if the screen size is smaller than 800px wide or so.
A: If there is no enough room on the right side of your browser windowdrop down menu list submenus will be shown on the left side.
Q: For the dhtml tree that I purchased, can I choose what menus will be expanded or collapsed when the user first comes to the webpage forthe first time?
A: You can expand some items by default.
Add '+' sign before items text in that case:
["+Javascript/DHTML Tree: XP Style","", "deluxe-tree.files/xpicon1_s.gif", "", "", "XP Title Tip", "", "0", "", "", ],
["|Home","testlink.htm", "deluxe-tree.files/icon1_s.gif", "deluxe-tree.files/icon1_so.gif", "", "Home Page Tip", "", "", "", "data-new.js", ],
"Javascript/DHTML Tree: XP Style" item will be expanded by default in that case.
Use var texpanded=1; parameter to expand all menu items by default.
Use function dtreet_ext_expandItem (itemID, expand) API function to expand the specificmenu items dynamically:
http://deluxe-tree.com/functions-info.htmlQ: We are registered users of the JavaScript Tree Menu software. Today I tried to use the Javascript API, but there is something I do not understand and want to ask for support.
First, I set up a very simple menu:
var menuItems=[
['Menu 1'],
['|Submenu 1'],
['Menu 2'],
['|Submenu 2'],
];
This menu is built via dm_init().
Then, I inspect the menu (in Firebug):
>>> dm_ext_getSubmenuParams(0, 0)
["dm0m0", 2, "", 0, 1]
>>> dm_ext_getSubmenuParams(0, 1)
["dm0m1", 1, "dm0m0i0", 1, 0]
>>> dm_ext_getSubmenuParams(0, 2)
["dm0m2", 1, "dm0m0i1", 1, 0]
Ok, there are three submenus. Now I am going to delete one of them:
>>> dm_ext_deleteItem(0, 0, 1)
"Menu 2" disappears on the screen, this works as expected. But now when I re-inspect the menu using the API, I find that the API reports exactly the same as before:
>>> dm_ext_getSubmenuParams(0, 0)
["dm0m0", 2, "", 0, 1]
>>> dm_ext_getSubmenuParams(0, 1)
["dm0m1", 1, "dm0m0i0", 1, 0]
>>> dm_ext_getSubmenuParams(0, 2)
["dm0m2", 1, "dm0m0i1", 1, 0]
So, it seems the report function continues to know about the original menu structure and reflects it. Am I using the API in a wrong way?
The problem I want to solve is to remove the entire menu dinamico dhtml, in order to rebuild it dynamically. Because I did not see a function aimed to this functionality, my plan was to delete all main menu entries subsequently until the main menu inspector no longer reports an entry. Is there (a better) way to achieve this?
A: Unfortunately, dm_ext_deleteItem() only change visibility of theseitems.
It doesn't delete them completely.
We'll try to fix it in the next versions of JavaScript Tree Menu.
Q: Our company has been using the trial version of JavaScript Tree Menu and was satisfied enough with initial integration efforts to acquire the license version.
We are interested in making our main dhtml rollover menu items a constant width, but the data.js parameters ( var menuWidth="800px"; var menuHeight="30px"; var smWidth=""; var smHeight="";) don't seem to give us that capability. We dynamically remove main menu items based on user roles and when we do the main menu always re-sizes and the remaining main menu item widths no longer match our sub-menu widths. We're able to adjust for this by using the API but that seems to be a lot of unnecessary coding. If we could keep each main menu item a fixed width, our sub-menu widths would not have to change.
Do you have information on how to accomplish fixed main menu item widths, even better would be an example?
A: Actually you can specify the width and of all or individual dhtml rollover menu items or submenus usingIndividual Item/Submenu styles.
