Hi all,
I have a date field data, as I can do to write from left to right and crush the value without having to click to focus the field?

Is that right now if you put the cursor right and want to change the value of that field,

I'm not leaving unless you select the value or delete it, but will not let me overwrite.

For example, in picture 1.jpg, if you wish to change the date field value could not as shown in the drawing, to do so would have to do what is in picture 2.jpg, that is to say,

select the value you want to change, and what I want to be able to change like this in figure 1, without selecting anything, just that when you type that crush me values.
