Appendix A (Editing menu_data.js)

The file menu_data.js is a set of pair: parameter = "value".
To each item of the menu there should correspond one or two parameters.
The first parameter (Required) looks as follows: td_* = "Item Caption"
The second parameter (Optional) looks as follows: url_* = "Item URL"
If the second parameter is present, after click by the mouse the user will be redirected
to page with appropriate URL value .
For example if the top line of your menu looks as follows:
Home Page Online Shop Services Company Info Contact Us Privacy Policy Help
You should add the following parameters in your menu_data.js

td_1 = "Home Page"
url_1 = "index.html"
td_2 = "Online Shop"
td_3 = "Services"
td_4 = "Company Info"
td_5 = "Contact Us"
url_5 = "mailto:info@somecompany.com"
td_6 = "Privacy Policy"
url_6 = "policy.html"
td_7 = "Help"
url_7 = "help.html"

Each item of the top menu can contain child items.
For example "Company Info" (td_4) can contain following items:

td_4_1 = "About our Company"
url_4_1 = "about.html"
td_4_2 = "Vacancies"
url_4_2 = "vacancies.html"
td_4_3 = "International Offices"
td_4_4 = "Forum"
url_4_4 = "news://news.somecompany.com"
td_4_5 = "Guest book"
url_4_5 = "guestbook.html"

In turn each child item of the top menu can contain own child items.
For example "International Offices" (td_4_3) can contain following items:

td_4_3_1 = "USA and Canada"
url_4_3_1 = "usaoffice.html"
td_4_3_2 = "Europe"
url_4_3_2 = "eurooffice.html"
td_4_3_3 = "Africa"
url_4_3_3 = "afrooffice.html"
td_4_3_4 = "Singapore"
url_4_3_4 = "singaporoffice.html"

And so on: Each item of your menu can has infinite sub menu levels!
The order of an arrangement of parameters in menu_data.js has no value.
But in each line there can be only one parameter (and its value).
Remember to enclose all parameters values in double quotes (").
