How can I add my own html input element like- Text Box, Text Area, Drop down, Save button in my Kibana dashboard UI

How can I add my own html input element like- Text Box, Text Area, Drop down, Save button in my Kibana dashboard UI.
And after clicking on Button (like- Save), I want to save these new html input values into Elasticseach database.

There's nothing like that in Kibana at the moment.

I moved your question to #elastic-stack:kibana so experts on that field might have suggestions to share and may be about the future.
