dropdown list with AutoPost Back (instead of "Go" link)

Hi, I used the DNN Links module to create dropdowns on our websites, and when I upgraded the Links module, the dropdowns don't work properly, in two ways.
1. The Use Permissions setting doesn't seem to work, so all the items in each list need to be explicitly set or they don't show.
2. There is no auto post back function, which means that when an item is selected in the dropdown list, the page doesn't go to the link. There is "GO" link next to the dropdown which you need to click after making the selection.

Number 2 is the real problem. Why was the post back function taken out of the Links module? Is there an easy way to restore this functionality, or if not, should I go back to using the old version of the Links module? It will be a ton of work to recode all my dropdowns if I can't use Links for this anymore.

Here's an example of the proper function of these Links/ Dropdowns (three dropdowns on the top right side of the page):
