Customization of the basic html elements

Hi guys,

we are trying to customize the select/dropdown or even the text-fields in our plugin and it seems to be very problematic.

i thought to use this out of date document
https://adobexdplatform.com/plugin-docs/reference/ui/elements/

but it seems like button with tooltip doesn’t really work.
https://adobexdplatform.com/plugin-docs/reference/ui/elements/tooltips.html

is there an updated source where i can see how i can customize the elements in the user interface?
