Page Order Query

Firstly, I apologise in advance if this is the wrong place to post this but I am very new to this. I am not technical but in my current job I have inherited the task of maintaining our website. Therefore, I had nothing to do with setting it up, so in all honesty I’m not really sure how the real nuts and bolts of it work. I’ve managed to do most of the things I need to do using help files and guides, but I’m now stuck.

We have a set of pages for our Events. These pages have a sidebar. With some help from the main forum I have now identified it as the Advanced Sidebar widget.

When I create new event pages (which I usually do by cloning and amending one of the existing event pages), I know how to manually enter them in the dropdown menu that appears under ‘Events’ in the menu that runs along the top of the site (Appearances – Menu) and can drag them into whatever order I want, but I am having trouble with the sidebar. The new pages I create seemed to magically appear in the sidebar without me having to do anything, and I now understand that Advanced Sidebar has been set up to do this, but I can’t control the order.

When I expand the widget, I can see a drop down for Page Order, and the only three options are Page Order, Title and Published Date. I was hoping for a drag and drop or similar (the order I want kind of groups events together by theme, which is only apparent in the text I type on the Event page so can’t see a way that this would be detected and recognised automatically). Is there any way to do this? (Also, is my clone-amend approach to new Event pages messing this up in some way?)

Many thanks in advance.
