Creating the theme options module

As we said in the previous chapter, to start a new Magento module, you have to create a module code folder under an appropriate code pool. We are going to use the local code pool for our module here.

We can use the same namespace used for the Widget module, BookStore, and create the module inside that folder. We are going to name it ThemeOptions.

- code
  - local
    - BookStore
      - ThemeOptions
        - etc

   <?xml version="1.0"?>
   <config>
     <modules>
       <BookStore_ThemeOptions>
         <active>true</active>
         <codePool>local</codePool>
         <depends>
           <Mage_Cms/&gt...
