Here is a example of how to create a standard dropdown:
If you want to access values inside items this is how the table for single items is made (just a example):
```lua
local mainFrame = basalt.createFrame("myFirstFrame"):show()
local aDropdown = mainFrame:addDropdown("myFirstDropdown"):show()
item = {
text="1. Entry",
bgCol=colors.black,
fgCol=colors.white
args = {}
}
```
