Accordions require three different templates - the 'accordion header code', 'accordion pane' and 'accordion footer code'
To set up a group of accordions, use the 'accordion header code' template
Populate the 'accordion pane' template to add content to your accordions
'Pane title' appears at the head of the accordion
'Pane content' is the text you want to appear within the accordion
Each pane must have a unique 'Pane ID' - the order of the panes on the live site is determined by where they appear in T4 content list rather than the 'pane ID'
Don't forget to add 'accordion footer code' after your accordion panes
