Clean up some Vue.js Vuetify autocomplete dialog code

I have a codepen project at [login to view URL] and I need some clean up and fix some items. 1. When the dialog opens the autocomplete should get focus. 2. Stop the menu from opening when input is selected. It should only open after three character is typed 3. Stop the menu from covering the input. 4. change the function of the enter key if there is an item selected trigger the apply button rather than opening the menu. 5. Clean up any code that is in Codepen. I am brand new to Vuetify Please look at the codepen code before you bid. From what I understand most of this is setting the autocomplete properties correctly. Number 4 may take a snippet of code. Look at the codepen console and it should help with number 5
