I would like to have description/addinional text inside text field. That text shouldnt disappear when user puts data into the field. It should just move along with it (like go more right and numbers/text that user has put in goes on left side).

Example:
Normal state:

```
 _________
|_m2______|

```

User puts some data in:

```
 ________
|_22_m2__|

```

The lines there just represents border of input field :) And that m2 is the text that should stay there always.

Hopefully you understood what i'm after. Trying to google it too, but not sure what are right words to descripe thing like that:)

Thanks.
