I think you need to save users' choice in the database. And when you show it, you make the PHP or whatever you use read the data from database. If the value of the option is equal to the value in database, then

<option value="xxx" selected="selected">xxx</option>

.
Otherwise, just write

<option value="xxx"></option>
