I have created a custom setting, navbar, which has 1 custom field, URL (data type URL). In this field I have 5 elements that link to apex pages (Home, chatter, cases, etc) but it could go down to 3 or even up to 10 depending on what is needed. I have these being displayed properly and dynamically but the issue is I would like them to be in a specific order. Currently they are listed in alphabetical. Is there a way I can attach/assign a number to each element so that I can sort the elements that way?
