Creating a button for expandable content
I've created some articles with expandable text, but the problem is that users have to click on the text to expand the content (see example: http://support.britishlegion.org.uk/app/answers/detail/a_id/1536).
I need to create a button for users to click on to expand/close the text, and the text on the button would change on click (see example of 'Show' 'Hide' button: http://m.england.shelter.org.uk/get_advice/homelessness/homelessness_-_an_introduction/what_is_homelessness).
Does anyone know how I can do this? Would be grateful for any help/advice.
