Could you please elaborate a bit more on what you are looking for? I am assuming that you would like to modify the width of a field. If I am correct please let us know what field you are looking to adjust.
To modify a textbox or text area field you can press the DESIGNER button on the top toolbar
In the window you can click a textbox field and all the properties will appear in the DESIGN tab
To adjust you may change the width property.
