Populate drop down list with JS

[masterlodi]

I have an MySQL table containing categories.
I have a drop down box with values of A-Z.
I have another drop down that I want to populate with categories

When a user chooses a letter from the drop down box, how can I populate the Categories drop down box

Either send the selection from the first dropdown back to the server (submit a form) and let it create the category drop down on the server side (not an optimal solution), or use an XMLHttpRequest to send the A-Z selection to the server, have the server send back only the categories required, and dynamically add the categories to the category drop down.
