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.
Q: For example if you use the Growing Goodness menu located under Media Categories the first category is Agriculture w/ a sub category "Community Supported (CSA)" it is the sub category that is an active link. Is it possible to have only the active link "Community Supported (CSA) underlined and not Agriculture? And the same for all the other active links in this menu, all that have hyperlinks assigned to them.
A: You can write your links in the following way:
["Channels","", , , , , , , , ],
["|<a class='menu' href='http://growinggoodness.com/callingfromthecoast.htm'>Eco-Friendly</a>","", , , , "_self", , , , ],
["|<a class='menu' href='http://growinggoodness.com'>Farmers Market</a>","", , , , "_", , , , ],
["Media Categories","", , , , , , , , ],
["|Agriculture","", , , , , , , , ],
["||<a class='menu' href='http://growinggoodness.com/csa.htm'>Community Supported (CSA)</a>","", , , , "_self", , , , ],
["||Movie Trailers","", , , , , , , , ],
["|||<a class='menu' href='http://growinggoodness.com/farmboymovie.htm'>Farmboy</a>","", , , , "_self", , , , ],
["|||<a class='menu' href='http://growinggoodness.com/strongrootsfragilefarms.htm'>Strong Roots, Fragile Farms</a>","", , , , "_self", , ,, ],
["|||<a class='menu' href='http://growinggoodness.com/therealdirtonfarmerjohn.htm'>The Real Dirt On Farmer John</a>","", , , , "_self", , ,, ],
And create a style:
A.menu {
color: #FFF;
text-decoration: none;}
A.menu:hover {
color: #FFF;
text-decoration: underline;}
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 Javascript/DHTML Tree such as in JavaScript Tree 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.
Javascript/DHTML Tree works fast, but 10000 is a large value. Please, try atrial version of Javascript/DHTML 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 Javascript/DHTML Tree into the <table> or <div>.
Q: I have looked through the FAQS on your site, but can’t find a clear answer to this questions:
Can a menu submenu dhtml be triggered to an open state upon onload?
I can get the top level menu over state to show, but the drop downs won’t open.
A: Unfortunately it is not possible to highlight the pressed menu submenu dhtml itemin JavaScript Tree Menu now. You can highlight the top items only.
