Q: It's simply not saving the state. Clicking the items on the menu is inconsistent. Sometimes it saves sometimes not.
It seems to be a lot worse in this area.
A: See, Tree Menu saves it's state using cookies.
But it can't re-save the same cookie file from different folders.
For example, if the tree from "website/page.html" saves it's state,the menu from "website/content2/page.html" can't read this state andit creates it's own state. The problem is that it's a standardfeature of browsers and Javascript can't control that.
Q: Can I install the menu using my buttons? I might be able to do it if the buttons used only one image, but they use two images. One is light and the other dark.
I also have some questions:
1) Will the menu stay in view when the user scrolls down?
2) I'm not even sure I care if the menu stays in view, because I believe that is done using php and is not good for SEO. The file that the search engines see is index.html while the file that visitors see is home.php. I think it would be better for SEO to have a normal .html page. Are you able to do that?
A: See how you should make image-based menus: if item text is empty, icon fields will be used as item images.
For example:
["", "index.html", "menu1a.gif", "menu1b.gif", "Home Page"]
1) You should use floatable feature.
See the following parameter:
var floatable=1;
2) You can generate search engine friendly code using Deluxe Tuner:
"Tools/Generate SE-friendly Code".
Q: I have a problem. How can we get the value of a parameter passed by the menu, when a menu item is clicked? For example I want to get the URL or file name to be open by the menu item when it is clicked.
I am talking about TREE menu.
A: If you want to open url or a file when you click on items of the tree menu you can write, for example:
var tmenuItems = [
["+DHTML Menus","http://dhtml-menu.com", "images/xpicon1.gif", , , "DHTML Menus", , "0", , , , ],
["|Save as...", "javascript:OpenFile('file_name')"]
];
Q: I am using cross frame menu dropdown. I have three frames: Top, Left and main (middle).
I am using the script and data from your sample file; it works fine. Only problem is submenu is offset to the right. It does not show up exactly down below the top menu.
What could be the problem?
A: JavaScript Tree Menu doesn't work correctly (incorrect submenu position) if youhave complex frame structure.
The problem is in a structure of your frameset.
Mozilla browsers can't determine absolute coordinates for a frame, so submenus drop down with an offset.
You should create, for example, the following frameset structure:
--|------------
| menu
--|------------
|
| submenus
|
Now a top row has 2 columns and all browsers can determine a width of the 1st column in the second row.
You should write init function in the following way in that case:
dm_initFrame("mainframe",1,3,0);
