Text area with Scroller

Hi,

I am building a course where there is a text area with a scroller is needed, the text area also has some html elements like alignments etc. If I use a table type with a single row and a column that removes all the html elements, displays as long text. The solution I have come up with is using an exportable text area which shows the text as 100 percent size and html elements. I need to remove the text input box from exportable area text and the third slideshow slide it autoadds,  is there a way to remove this text area?

thanks in advance
