Creating a listing page

Hi Bubblers,

Im new here and I am trying to create a listing page similar like this sites: http://chimpgroup.com/demo/?theme=directory and https://demo.templatic.com/locations/ . I created an admin page where i create the categories and sub categories and the link to the website.

Even though i did all the tutorials on here im still struggling on how to save the informations on the database using the workflow.

My question is, how can I save the categories in the dropdown to the database. Do i have to save the categories in ‘Type’ and the subcategories and links in ‘field’ ?
How can i make it to automatically display a new created category in the repeating group (index page).
And how can i make it that when the user click on a subcategory he get the results from the search displayed in the repeating group.

Thanks in advance
