Hi there,

Thank you for reaching out to us.

I recommend adding different rows for each index letter (A, B, C.....)  and dividing each row to three columns. You will then use the heading element to add each letter (A, B, C... ) then use the text block element to add the individual index links.

I hope this info helps.

Kind regards,

Hi there,

You're welcome.

 Should you have any further questions or encounter any difficulties along the way, please don't hesitate to reach out. 

Best regards,
