How do you create a collapse/expand connection between two paragraphs in Word (2013)?
On occasion, I have seen Word documents which include the ability for collapsing or expanding certain paragraphs with a single click of the mouse. In these cases, a small triangle is present (just to the left of the "parent" paragraph) which when clicked, collapses or expands (hides or unhides) some number of "child" paragraphs below the paragraph with the triangle.
In the uncollapsed state, the triangle is gray, points down and to the right, and is only visible when mousing over its corresponding paragraph. In the collapsed state however, the triangle is white (ie only its edges are visible), points directly to the right, and is always visible.
How do you create a collapse/expand (parent/child) connection between two or more paragraphs?
Is the connection in any way dependent of the styles assigned to parent & child? In other words, must both paragraphs be the same style or can there styles differ or does it not matter?
How do you designate the number of "child" paragraphs to collapse below a given "parent" paragraph?
