Accordion Icon?

[jfine24]

Hi,

I am looking for an icon that display on/off accordion function on the webpage. The default is to have all the list expanded with its sub list. Some pages have over 200 items in the listing. The user might want to be able to control the list by collapsing or expanding them. I will use bxs-minus-square and bxs-plus-square to collapse and expand the listing. I need an icon on the top of the page to allow the user to turn on or off the accordion function. That would be great if you are able to create one. Thank you!

Regards,
