Expanding a Single Line Text field to length of the input text

Expanding a Single Line Text field to length of the input text

I am using a Single Line Text field into a Fillable document and in the fillable pdf version if the length of the text is greater than the field size, the text is hidden.
The default setting of length is 30 and I have made it 100.
Is there a way of making the Single Line Text field expand beyond 30?
I don't want to use the multiple line option if possible
