I can't seem to find anything similar to this right now, but I am pretty sure I have seen something like it before.
I am currently able to use either input or textarea html tags and the placeholder attribute to get something close to what I want, but I also want to provide the user the ability to copy the placeholder text and enter/paste it in the same box as an entry. Is this possible?
An use case would be a place holder of a common directory path: box1@mtk:/path/to/data/20180202_TextFile.txt
I want the user to be able to copy and paste "box1@mtk:/path/to/data/" into the box so they just have to change the text file name.
I can't force value to be the placeholder because I don't want users accidentally submitting forms without modifying all fields.
So is it possible to have selectable / copyable placeholders?
