hi,
I have added my question , my main Aim at the end of this explanation.

I have two tables.

1.ProgramClips ( id, progSummary, category, videoFile)PRIMkey = id.
and each id may have 2 or three categories.

2.Category( number,category).
categories are :
Beef , diary, horticulture etc;

I am using PhpMyAdmin as the interface for the mySql Database.
The PhpMyAdmin uses a text filed to show the values of the category.

If there are two or more categories for example Beef and Diary then "Beef | Diary" is shown in the text field.

Now I want to change that text field into a drop down list and enable multiple selection of the values. And if I want to update the category field in program clips I will select one or more values in the drop down list and do some programming to put a pipe symbol in between the selected values ( in order to make MySQL to understand and interpret).

::::::::::::::::::::::::::::::::::::::::::::::::::::::

My Question in Precise is
1. is there aby way in realation databases that the values that appear in the FORM are the values from the 'categories' table. If I add more categories then those values can be automatically added into the FORM from whcih I update the 'category' field in 'programClips' table.
