How do we wrap the text with in a structured array or put a horizontal scroill bar?
Not 100% sure what you mean.
In Form Designer, the form element 'Text Area' will wrap the text on the screen when the characters reach the end of the line. If you have a form element of 'Text', (or Combo Box or ComFill), the text won't wrap, even if you have set an 'Array Length' parameter on the form element in Form Designer.
I don't think there's any form element that generates a horizontal scrollbar when the text length becomes too long... I think the user just has to manually move the cursor through the data on the field.
But again, not 100% certain I understand your question
