    1. COwhat do you mean static? If you are sennding values from selectbox you will need <option value="x">. Then in the php file just connect o db and query the db for the desired value and echo the result in the desired manner.

    3. COYou wrote "and i want to be done static in php but using database" so you got me confused. Well then you will have to have this list of countries in text file or csv or whatever and format it in the way so that you can read it easily. For example if you use text file maybe you can format it like this Country:City; then read the file explode() it so that you get array and search for needed values. Search the web for reading txt files and explode() function

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
