Hide/Reveal Divs based on UL List - cookied state

I have an existing drop down that displays hidden divs, but I need to cookie the selection so that when you go to another page with a drop-down, it defaults to that selected state.

https://www.bankofthewest.com/personal-banking/savings-accounts/savings-and-moneymarket/online.html 

I also have code that I used before that displays a drop down based on a UL list that, when selecting the state, takes you to another page. This code sets a cookie so that when you go to another page, the default is the state you selected.

Is there a way that I can combine the two? I would like the look of the second version and cookie of the second version but instead of going to another page, I want it to reveal a hidden div.  See code below.

<h1 class="header">Checking</h1>
<div id="option-selector" style="padding-bottom: 0px">
<h2>With a variety of features and benefits, you can find the checking account that offers the best value and the right fit for you</h2>
</div>
<h2 class="header compare wrapper" style="height: 20px;">
<div class="left">Compare Checking Accounts:</div>

<form>
			<div id="compare-select" class="select hide-dropdown">
				<div class="wrapper">
					<a onClick="return observeOpener(this);" href="" class="dd-opener">Select a state</a>
					<a onClick="return observeOpener(this);" href="" class="dd-opener pulldown-arrow"></a>
