Q: How can I use Danish characters in my dhtml menu bars?
A: You should turn on "Tools/Use utf8 encode" property.
In that case your data file will be saved in UTF-8 encode. So, you
should set UTF-8 encode on your page too
<meta http-equiv="Content-Type" content="text/html"charset="UTF-8">
If you don't want to use UTF-8 encode on your page you should turn off
"Tools/Use utf8 encode" property, save your data file and manually
change your letters in any text editor.
Q: I’d like to know how to populate the navigation bar menu from a database?
A: Please, see the example of .php file.The content of .php file depends on your database structure.
<?php
// The example for PHP/MySQL.
// MySQL database has the table "menuTable" that contains data for menu items.
// The table has the following fields:
// 1. "text" - item text
// 2. "link" - item link
// 3. "icon1" - item icon (normal state)
// 4. "icon2" - item icon (mouseover state)
function getMenuItems()
{
$jsItems = '';
// Select all records from table "menuTable"
$allItems = mysql_query('SELECT * FROM menuTable;');
// Extract items data from database and build Javascript code for menuItems
while ($itemData=mysql_fetch_array($allItems))
{
$jsItems .= '["'.$itemData['text'].'", "'.$itemData['link'].'", "'.$itemData['icon1'].'", "'.$itemData['icon2'].'"],';
}
// Return Javascript code
return $jsItems;
}
?>
<script>
var menuParam1 = value1;
var menuParam2 = value2;
var menuParam2 = value2;
...
var menuItems = [
// Write Javascript code for menu items
echo getMenuItems();
?>
];
</script> 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: Maybe have some code that would tell the tree menu html to expand on that particular page?
A: On your pages you should call the following function/functions to expand/highlight items,
for example:
<script>
dtreet_ext_expandItem (dtreet_ext_getItemIDByIndex (0, 0), 1);
dtreet_ext_setPressedItem (0, dtreet_ext_getItemIDByIndex (0, 1));
</script>
