Open Jquery Accordion Using Anchor Tag Within Same Page

I've searched for hours trying to find a solution for this but I can't quite figure this out. Any help would be appreciated. I'm starting to understand jquery a bit but it's mostly

Solution 1:

here is a great explanation how to do it jquery ui widget accordion open with external button control . On click event of some tag:

$('.some-tag').on('click', function(){
    $( ".accordion.product1" ).accordion({active:0});
});

active:0 the 0 is index of the accordion that you want to open.

UPDATE

Add this to accordion:

$('.accordion.product1').accordion({
    //... optionscollapsible: false
});
