数据库设计 - 最佳实践 - 一个用于Web表单的表下拉选项或每个下拉选项的单独表

I'm looking at the best practice approach here. I have a web page that has several drop down options. The drop downs are not related, they are for misc. values (location, building codes, etc). The database right now has a table for each set of options (e.g. table for building codes, table for locations, etc). I'm wondering if I could just combine them all into on table (called listOptions) and then just query that one table.I'm looking at the best practice approach here.
